BJ I think it would be good if we could somehow organize these links better I don't think it works well to just have a ton of ideas and no direction. Like the intended purpose of the site the idea seems to be to expediate the process of reaching our goal ASAP. Organization has been what's made this site great from the beginning I think dumping tons of information is akin to what lawyers do to confuse the other guy! So I don't know what would be the best way to organize this stuff but...than again it is directly from the source...

[Bruce Klein]

We do have the ImmInst Links Database as an idea.. however, this would take some administration to keep in order. If anyone wishes, the admin page is here, pass is 'under'.

[Lazarus Long]

You are welcome to attempt to consolidate and collate the info but my purpose in creating this thread is a running historical archive reflecting the global nature of nanotech research. These articles are developing in real time and this thread is a single source for that purpose.

Organization is often like beauty, in the mind of the beholder. There is nothing stopping you for example to follow up ion all the articles say referring to applications as nano polymers and then updating them with current searches and building a thread around that theme. There is also no contradiction to what I am doing here,

Have you ever scanned a card catalog not for a specific text but to see what texts on a subject have been written? There is not a single course to comprehension, no straight line that works for all, there are however many ways to organize such endeavors and all can be helpful.
BTW, I try to credit Gina in each post if you take the time to read the header and footnote.

[Lazarus Long]

I should add that from time to time I include other digests like the one that follows. It is also from Gina's site.

One reason I am choosing to just shot gun the info at this time is that we are looking at an emerging field of science. It is a field of science that will inevitably cause the reorganization of much of how we look at what is the current model for the division into scientific genre now. The idea of including genetics as a subset of nanotech is one example of this reorganization but the various aspects are much more profound than even that idea.

The various threads are where some of the material presented here can be better developed and the original links should be included when ever possible, or better yet updated as subsequent review permits.

Homeland Security Gets Small. How Nanotechnology May Aid Anti-Terrorism. Ultimately, fighting the war on terrorism may have less to do with giant aircraft carriers and more to do with atomic-scale detection and prevention systems. Nanotechnology, which is expected to transform everything from computer processors to drug delivery systems, may also be the key to homeland security, argues a new book. In Nanotechnology and Homeland Security: New Weapons for New Wars, Mark A. Ratner, a professor of chemistry at Northwestern University and a noted expert in molecular electronics, and his son Daniel Ratner, a high-tech entrepreneur, claim that current research in nanotechnology will lead to intelligent sensors, smart materials, and other methods for thwarting biological and chemical attacks.

Hitachi Set to Plant It's Own 'Nanostamp' on the Medical Market. Hitachi's Advanced Research Laboratory (ARL) is getting ready to commercialize a low-cost "nanostamp" technology for medical applications. Hitachi's process creates "nanopillars" with extremely high aspect ratios (narrow relative to height), a feature that the company believes will prove useful for biochips and other applications, according to Akihiro Miyauchi, a senior researcher at Hitachi. The technology uses a silicon "stamp" that presses onto a polystyrene-based polymer film, producing nanopillars that are extremely long and thin, about 3 microns in height. (Smalltimes 12/30/03)

Entering the Nano-Age? By Glenn Reynolds. Last week, I wrote about the EPA Science Advisory Board meeting where nanotechnology was discussed. I learned a lot of interesting things there, but one of the things that I learned is that, even for people like me who try to keep up, the pace of nanotechnology research is moving much too fast to catch everything. One of the documents distributed at that meeting was a supplement to the President's 2004 budget request, entitled National Nanotechnology Initiative: Research and Development Supporting the Next Industrial Revolution. I expected it to be the usual bureaucratic pap, but in fact, it turned out to contain a lot of actual useful information, including reports of several nanotechnology developments that I had missed. The most interesting, to me, was the report of "peptide nanotubes that kill bacteria by punching holes in the bacteria's membrane." You might think of these as a sort of mechanical antibiotic.

The next high-tech frontier? For Donn Tice, the path to the new world of nanotechnology leads through the old world of apparel manufacturing. Nano-Tex's chief executive officer has traveled the globe this year selling his Emeryville, Calif., company's nanotechnology chemical formula that makes fabrics stain-resistant...Nano-Tex's Nano-Care product is more than just a coating that repels stains. It changes the fabric itself on a molecular level, embedding it with tiny, floppy, hair-like fibers that themselves are attached to a common spine. Just as hair keeps rain from penetrating a dog's coat, the "nano whiskers" in Nano-Care's chemical mix keeps stains from soaking into clothing.

2003: The Year of the Straw NanoMan. Ronald Bailey, in his very reasonable piece about the "growing peril" of a nanotechnology moratorium," asserts that anti-nano activists "cannot be lightly dismissed."I agree to a point, having made similar assertions myself, but after speaking and listening to a number of business and government leaders, I can't help but think that activists like Pat Mooney of the ETC Group might be the best thing that's happened to the nanotech industry. When it comes to the environmental debate, the handful of people who call for a moratorium on nano research conveniently play the role of the straw enemy of nanoprogress, since their pseudoscience can easily be attacked. That is what I was thinking as I listened to Phil Bond, the U.S. Commerce Department's undersecretary for technology, give an eloquent speech recently in Chicago.

(Written by Douglas Mulhall, author of "Our Molecular Future." Incorporate
disassembly into every self-assembled nanotech product. There is a growing
mantra in the nanotech community that molecular nanotechnology (MNT) and its
precursors will clean up the toxic mess left by older technologies, then produce
clean energy and materials to replace them. Yet each time that I suggest
building such features into nanotechnology from the start, the reply is: "We've
got other things to worry about such as how to build the darn assembler and keep
it militarily secured, and besides that it might be hard to achieve such
perfection with early versions." This is disturbingly reminiscent of "nuclear
power will give us clean limitless energy, and don't worry, we'll deal with the
byproducts later because we'll have the tools by then." However, we can avoid
such risks from the start by using "self-regulating assembly" and "disassembly."

(Glenn Harlan Reynolds) The Nano-Ostrich Approach Doesn't Work. Ostriches don't
really bury their heads in the sand when confronted with danger. People,
however, sometimes do. Certainly that seems to be what's happening with the
nanotechnology industry. Last week, I wrote about prospects for nanotechnology,
and in particular about what I saw as the nanotechnology business community's
rather shortsighted efforts to dampen public debate on the subject. I thought it
was rather clear that my column, like all my nanotechnology writings, came from
a generally pro-nanotechnology standpoint, though I concluded: [W]hile I feel a
certain degree of sympathy for the dinosaurs, I think that if the nanotechnology
business community, because of the PR strategy that it has chosen, finds itself
scissored between the scientists and visionaries on one side, and the
environmentalists on the other, it will have cause to regret its rather
shortsighted PR strategy. It's too early to predict that outcome now. But, like
a lot of things relating to nanotechnology, it's not too early to worry about
it. In fact, it wasn't very much too soon at all -- because if you read this
Washington Post article by Rick Weiss, which appeared just a few days after my
column, you can see exactly that scissoring starting to take place. The article,
which is well worth reading (as is this sidebar on near-term applications),
shows the industry being criticized not only by environmental groups, but by
long-time nanotechnology boosters. And, in fact, it suggests that Monsanto's
problems with public fears regarding its genetically modified organisms are a
harbinger of what might happen with regard to nanotechnology. (TCS 2/4/04)

affect human health? At the present no scientists anywhere are able to answer
this." Dr. Jiang Lei also tells us how to protect ourselves in nano research.

Nanotechnology is area giant. Here's one of the "Look Ma, no hands" perks of
owning a stain-repellent shirt: Fill up the pocket with water and watch it hold
the liquid like a cup, without any leakage. "All you need is a straw," quipped
David Offord, chief scientific officer at Nano-Tex, the start-up that developed
the technology, during a demonstration. Naturally, the regular marketed
advantages of owning stain- and liquid-repellent clothing come in handy, too.
Enhanced through nanotechnology, the material allows even the clumsiest person
who dribbles ketchup or spills coffee to wipe it off as easily as brushing off
cookie crumbs. Here in the East Bay, nanotechnology has become the fabric of our
lives. (ContraCostaTimes 2/1/04)

(65nm Chips discussion). Semiconductor companies are becoming increasingly
confident about making 65 nanometer chips. Some are even stating that the 90 nm
to 65 nm transition will be easier than the 130 nm to 90 nm shift. Many of the
technical problems associated with 65 nm chip production have been solved, and
Intel has already demonstrated 65 nanometer SRAM chips. Intel will probably
create the first prototype 65 nanometer microprocessors sometime in 2004, and
hopes to have volume production of 65 nanometer chips by 2005. 65 nanometer
chips will be made with 193 nanometer lithography, and will suffer from severe
electrical leakage issues. As a result, chipmakers are making a concerted effort
to introduce multi-gate transistors at the 65 nanometer node.

Virtual Nanotech. Modeling materials one atom at a time. It's hard enough to
thread a needle. Imagine trying to manipulate threads and needles miniaturized
to one-millionth the normal size. Now, you're thinking like the emerging group
of nanotechnologists whose growing dexterity at fashioning new materials and
devices may eventually improve every arena of technology, from aerospace to drug
development. While many researchers focus on developing tools for working on
nanoscale materials, others are pursuing a virtual pathway toward nanotechnology
applications. As ever-more powerful computers have become ever more affordable,
computational nanoscientists can readily simulate materials atom by atom.

Nanopore Analytical Instrument Developed by UCSC's new Department of

biomolecular engineering is the nanopore analytical instrument being developed

nanopore instrument is built around a membrane containing a tiny hole just a few
nanometers in diameter (a nanometer is one-billionth of a meter). An electrical
field drives single molecules such as DNA through the nanopore. As a molecule
enters the pore, it produces an electrical signal that provides information
about its concentration, identity, and composition. The pore itself is a
naturally occurring bacterial toxin made of self-assembling protein molecules.
Potential applications of the nanopore device include ultrarapid DNA sequencing.

Tiny new rulers for the 'ultrasmall'. Scientists can sometimes get away with
approximations. What's a few million years when you're calculating the age of
the cosmos? But engineers need precision. They cannot reliably make what they
cannot measure. And in the world of nanotechnology, where a billionth of a meter
can make a huge difference, they've had a tough time. Now they're beginning to
get some help. Three recently reported achievements show how researchers finally
are mastering the exquisite precision needed when devices are built atom by
atom. For example, MIT scientists have come up with a tool to make what they
call "the world's most precise rulers - with 'ticks' only a few hundred
billionths of a meter apart." It can lay out a grate of lines and spaces across
a large semiconductor wafer with unprecedented speed. (csmoniter Feb 2604 issue)

smallpox virus, anthrax and ricin, and also in routine indoor air
ventilation applications such as in buildings and aircraft cabins..."When
the aerosol particles come into the device they are charged and trapped in
an electrical field," Biswas explained. "Any organic material is oxidized,
so it completely deactivates the organism."...Anthrax is nasty stuff. An
environmental engineer at WUSTL uses smart catalysts in his device that can
detect the airborne presence of anthrax and other bioweapons and disable it.
On the walls of the device, Biswas has coated nanoparticles that catalyze
the oxidation. These nanoparticles are "smart" objects that are turned "on"
and "off" by irradiation.

Three university scientists are developing a prototype device that they say
will allow patients on blood thinning medication to take their own
blood-clotting readings at home. The cell phone-sized device would work like
the machines that diabetics use to check their blood glucose levels,
according to the Drexel University researchers, who recently founded a firm
called BioSensus to develop and market the NanoAcoustic Blood
Analyzer."Patients become more confident and in control of their own fate by
taking their own readings," said J. Yasha Kresh, a professor at Drexel's
College of Medicine. The researchers said that their device is different
from other blood analyzers on the market because it can be targeted to read
the amounts of specific kinds of proteins in the blood that are involved in
clotting and bleeding. Other blood-testing machines on the market use a
system of capillary-sized tubes to determine blood's thickness by measuring
how quickly it works its way through the tiny mazelike structure. The Drexel
scientists say their nearly submicroscopic technology _ analyzing particles
1/75th the width of a human hair _ would more easily adapt to a wide variety
of uses other than blood thickness and to adjust for as-yet undiscovered
medicines. (NEPA3/5/04)

control genes. The breakthrough is expected to help pharmaceutical companies
speed and enhance the process of screening candidate cancer drugs. In a
study published in the February issue of the respected science journal
Nature Biotechnology, the researchers reported they used quantum dots
developed and manufactured by Hayward-based Quantum Dot Corporation (QDC) to
provide prolonged, real-time visualizations in living cells of the signaling
mechanisms of the erbB family of receptors, the targets of many cancer
drugs. Quantum dots are nano-scale crystals of semiconductor material -- up
to ten-billionths of a meter in size -- that glow in several different
colors, depending on their size, when excited by a light source such as a
laser. The dramatic video-clip images mark the first time researchers have
been able to see moving images of a cell's basic means of communication with
its environment. (Businesswire 3/1/04)

Nanotechnology is already a billion-dollar industry, and it's barely out of
the lab. The U.S. government plans to plow nearly $1 billion into nanotech
research during fiscal 2004, and it'll add $3.7 billion more between fiscal
2005 and 2008, said Clayton Teague, director of the National Nanotechnology
Coordinator Office, a government department that facilitates cooperation
between academic researchers, corporations and other government offices.
"Our federal government is committed to the promise of
nanotechnology...without compromises to the public health," Teague said
during a speech Monday at the Nano Science and Technology Institute's
Nanotech 2004 trade show here. "With all that support, (the government and
lawmakers) are really looking to this field to be a major contributor to our
economy over the coming years." (ZDNet 3/8/04)

Nanoscale Elevator Raises the Bar. Complex device demonstrates progress in
designing and building molecular machines. complex nanoscale machine that can
shuttle molecules like a tiny elevator has been designed, built and operated.
Developed by Italian and American researchers, the tiny, chemically driven
machine consists of a platform with three rings, each of which is attached to
the leg of a tripod-like structure. At just 2.5 nanometers high and 3.5
nanometers in diameter, the elevator represents a big advance for the
construction of molecular machines, experts say.

Solar-powered Molecular Motor Built. Could provide parts for nanoscale machines.
The first molecular motor has been created that runs on electricity or light.
Developed by Frederick Hawthorne and colleagues from the University of
California, Los Angeles, the tiny motor could power machines on a scale smaller
than biological motors such as flagella. "Given the existence of biological
motors, the interest of chemists in designing molecular motors stems from the
challenge not only of making even smaller nanomachines that perform controllable
motion, but also of creating systems that can be powered with light or
electrical energy, rather than depending on the delivery of ATP," say the
researchers. (Betterhumans 3/18/04)

Yarn spun from nanotubes. Tiny tubes may yield ultrastrong fibres. Scientists
have spun long, rope-like fibres from nanotubes. Their environmentally friendly
method could be tweaked to make high-strength threads for use in engineering.
The long ropes could even lead to futuristic applications such as a space
elevator. Alan Windle and colleagues at the University of Cambridge, UK, made
their tiny twisted ropes by winding freshly made nanotubes onto spinning rods as
they came out of a furnace. The nanotubes are hollow strands of carbon just 30
millionths of a millimetre or so wide - around 5,000 times thinner than a human

'Nano-Lightning' Could Be Harnessed to Cool Future Computers. Mechanical
engineers at Purdue University are developing a new type of cooling technology
for computers that uses a sort of nano-lightning to create tiny wind currents.
The researchers have shown that the underlying concept for a "micro-scale
ion-driven airflow" device is sound and have recently filed for a patent. "This
is a groundbreaking idea," said Suresh Garimella, a professor of mechanical
engineering at Purdue who is working on the device with Timothy Fisher, an
associate professor of mechanical engineering, Daniel J. Schlitz , who recently
earned a doctoral degree from Purdue, and doctoral student Vishal Singhal.
Schlitz and Singhal have created Thorrn Micro Technologies Inc. to commercialize
the cooling system. Future computer chips will contain more circuitry and
components, causing them to generate additional heat and requiring innovative
cooling methods. Engineers are studying ways to improve cooling technologies,
including systems that circulate liquids to draw heat from chips. Using a liquid
to cool electronic circuits, however, poses many challenges, and industry would
rather develop new cooling methods that use air, Garimella said. (Ascribe

'Nanograss' Turns Sticky to Slippery in an Instant. With possible applications
in everything from microscopic plumbing to slick boat hulls to switches for

droplets like a newly waxed sports car, but, at the flick of a switch, turns
absorbent like a "quicker picker upper" paper towel. Depending on the chemical
structure of a solid, water and other liquids either cling to it - making it wet
- or it repels them. Usually a surface is absorbent or repellent, but not both.

said Dr. Tom N. Krupenkin, a scientist at Lucent Technologies' Bell Labs who led
the research. "If you can change that on the fly, it opens up applications
everywhere." (NYTimes 3/16/04)

Harnessing Nanotechnology. As field develops, scientists gather to take stock and look to the future. The field of nanotechnology is getting a lot of attention these days. Many scientists and policymakers are excited over the potential impact of this field on areas such as energy, public health, and the environment. But despite this bright future, it's the potentially harmful implications of the science as detailed by some media outlets and science-fiction literature that is garnering the interest of the general public. Creating an environment that recognizes and addresses public concern, while encouraging continued research and development, is a key challenge facing the nascent field. That challenge was a major topic of discussion at a recent nanotechnology conference. Held in Washington, D.C., in early April, the meeting, called National Nanotechnology Initiative: From Vision to Commercialization, brought together approximately 400 scientists from academia, industry, and the government to assess the state of the field and discuss its future direction.

Are Nanobots Fiction or Reality? (By Chris Phoenix of CNR). As far as we know, nanoscale machinery is possible, and we could see molecular manufacturing within a decade. Nanotechnology is a diverse collection of fields. It promises many things that haven't been built yet, such as molecular electronic computers, new kinds of medicine, and nanobots. As far as we know, nanobots are quite possible-no more "fictional" than the others. However, nanobots are special for three reasons: They were the first kind of nanotech to be called "nanotechnology"; they can be used for general-purpose manufacturing, including building more manufacturing capability; and they're associated with scary ideas, so a lot of nano bureaucrats like to claim they're impossible.

Getting Molecules To Do The Work. The era of nano-manufacturing is being born in hundreds of labs that are racing to perfect a technique called self-assembly. If you just listen casually to a description of what Sandia National Laboratories has been working on, you would think it had wasted its time reinventing the wheel: It has developed a robot that can walk and pick up and deliver loads of cargo. In an age of advanced assembly and landings on Mars, that hardly sounds impressive -- except that Sandia's robot is a molecule. Called a motor protein, it has two little feet on one end and a tail that can grab things on the other. Once a special chemical is added to the solution in which it resides, the protein begins moving along strands of fiber that are one-fifth the width of a human hair, says Bruce Bunker, a Sandia researcher who's in charge of the project.

A Rose By Any Other Name? Nanotechnology may be the next big thing, but the sweet smell of success is being used to promote nearly worthless stocks, charges Asensio & Co. The New York City-based investment banking firm has asked New York State Attorney General Eliot Spitzer to investigate misuse of the nano label. Asensio charges that nanotechnology "has become a favorite, and successful, term among America's most fraudulent stock promoters." The firm has reason to want to stop such hype: It makes money by publishing critical reports on stocks that it believes are overvalued and "short selling" them-betting that they will drop in price.

Spray-on electronics move closer to reality. If recent research projects bear fruit, it won't be too many years before magazines play videos and semiconductors roll out of inkjet printers. Workers at Xerox and TDA Research independently unveiled methods this week for making transistors out of plastic rather than silicon, in ways that could be commercially viable. Such a shift in materials could drastically reduce the cost of computer displays because chipmakers would not have to build multibillion dollar factories to make semiconductors to power these devices. Just as important, it could greatly expand the range of objects that connect to the Internet, because electronic connections would be handled by a thin film or moldable material, rather than rigid chips. A thin screen could be bound into a magazine, for instance, and connect wirelessly to a Web site, or plastic soda bottles could transmit signals to inventory devices.

Nanotech's Chemotherapy Cure (Josh Wolfe). In the world of modern medicine there are few more imprecise and drastic measures than chemotherapy as a treatment for cancer. In most cases the process involves poisoning a patient's system with toxic chemicals in an effort to kill malignant cancer cells. Anyone who has personally suffered through chemo or seen a loved one suffer can attest to its destructive and debilitating side effects. Unfortunately, one of the causes of these severe side effects comes not from the anti-cancer drugs themselves, but from the solutions used to dissolve them. When a drug won't dissolve in water, another solvent is often used in its place; occasionally the side effects of the solvent cause more discomfort than the cancer-killing agent. Scientific researchers working with nanoparticles, 1/100th the size of a red blood cell, may have discovered a solution to chemo's "solution" problem.

Twisty Tweezers. Using only a laser beam, researchers can spin a microscopic bead, but they can't measure or control the twisting force. Now reports in the September 2003 Physical Review A and the 14 May PRL demonstrate that the twisting force, or torque, can be measured by analyzing the light passing through the object. The PRL paper also shows how to control the torque by creating what the authors call an "optical torque wrench." The technique could be useful for exploring cellular machinery such as molecular motors or the proteins that replicate DNA.

Carbon-50 makes its debut. Physical chemists in China have made carbon-50 molecules in the solid state for the first time. Lan-Sun Zheng and colleagues at Xiamen University, and co-workers at the Chinese Academy of Sciences in Beijing and Wuhan, prepared the molecules - which they describe as a long sought little sister of carbon-60 - in an arc-discharge technique involving chlorine. The result will allow scientists to study the properties of carbon-50 with a view to exploiting its unusual properties. The method developed by the Chinese team also opens the way to making other small, cage-like carbon molecules or "fullerenes" (S-Y Xie et al. 2004 Science 304 699).

The spooky place where art meets science. Stem-cell revelations, nanotechnology used to make molecular graffiti -- they're at the Subtle Technologies festival of art and science. Ask Jim Ruxton and Tania Thompson what they think about artist Georges Braque's subversive remark that "art upsets and science reassures," and they immediately spring into a defense of the rationale for their little-known, but hugely quirky, festival of art and science called Subtle Technologies. While there are differences in the two communities, says Ruxton, an electrical engineer turned electrical artist/inventor in an artistically loud pink shirt, today things may be the reverse of Braque's statement.

Edwards thinks an initial version could be operating in 15 years, a year earlier than Bush's 2020 timetable for a return to the moon. He pegs the cost at $10 billion, a pittance compared with other space endeavors...Edwards' elevator would climb on a cable made of nanotubes - tiny bundles of carbon atoms many times stronger than steel. The cable would be about three feet wide and thinner than a piece of paper, but capable of supporting a payload up to 13 tons. The cable would be attached to a platform on the equator, off the Pacific coast of South America where winds are calm, weather is good and commercial airplane flights are few. The platform would be mobile so the cable could be moved to get out of the path of orbiting satellites. (Yahoo 6/26/04) http://story.news.ya.../space_elevator

X-Rayed Movie. A research team has produced the fastest movies ever made of electron motion. Created by scattering x rays off of water, the movies show electrons sloshing in water molecules, and each frame lasts just 4 attoseconds (quintillionths of a second). The results, published in the 11 June PRL, could let researchers "watch" chemical reactions even faster than those viewable with today's "ultrafast" pulsed lasers. X rays can reveal atomic-scale spatial details in liquids and solids because their wavelengths are as short as the distances between atoms. Experiments typically involve aiming an x-ray beam at a sample and measuring the intensity of scattered x rays at each angle around the sample. In so-called inelastic x-ray scattering, researchers also measure the energy of the scattered rays, since x rays sometimes lose energy as they ricochet off of electrons. In theory, the scattering angles lead to nanoscale still pictures, while the energy loss data tell researchers how the pictures change with time.

Nano Killers Aim at Mini Tumors. A company called Kereos is developing a pair of nanotechnologies to identify tumors that measure just 1 mm in diameter, then kill them with a tiny but precise amount of a chemotherapy drug. The technologies, if approved by the Food and Drug Administration, would not only find cancers in their earliest stages before they can do damage or spread, but also deliver a small amount of a drug targeted directly at tumors, which would cause little or no side effects.

Clothes launder own fabric. In the classic 1951 film, The Man in the White Suit, Alec Guinness played a scientist who invents a fabric that never gets dirty or wears out. A chemist's pipe dream perhaps, but the prospect of self-cleaning clothes might be getting closer. Scientists have invented an efficient way to coat cotton cloth with tiny particles of titanium dioxide. These nanoparticles are catalysts that help to break down carbon-based molecules, and require only sunlight to trigger the reaction. The inventors believe that these fabrics could be made into self-cleaning clothes that tackle dirt, environmental pollutants and harmful microorganisms.

It's a small world. A hushed office in Building 8 at MIT stands at the cutting
edge of small things. Newly minted PhD Tim Hanlon, 27, points to a device called
the nano-indenter, and remarks, "Experiment after experiment, it never fails to
amaze me . . . and I've been working here for 4 years." A nanometer is
one-billionth of a meter. For most of history, such minute distances, the scale
where atoms lurk, have been invisible to humans, even though all activity in the
physical world really begins there. The nano-indenter contains a tiny diamond
tip that can detect the resistance and friction between atoms at the nano-level.
Hanlon and his boss, MIT professor Subra Suresh, often prod the tip into various
materials -- copper and steels, for example -- to determine how they might be
engineered at the nano-level to become stronger and more resilient.

Marlow turned Nano into a screenplay that is likely to become a movie, he notes

Singapore scientists find new way to use animal bones for human implants.
Singapore scientists have found a new way to process animal bones, and turn them into scaffolds that are as good as natural bones which can be implanted directly into patients. Inexpensive and easily available, this bone material could soon replace existing material now used for bone repair. This pig's bone was once
part of Dr Mao Pei-Lin's soup stock for her son. But it is now the bio-engineering scientist's research material. In the past, surgeons repaired broken bones by grafting human or animal bones that have been cleaned and purified with solvents under extreme high temperature. The problem with this process is - it is expensive, and the high temperature could change the original chemical components and structure of the bone. Another problem - the solvents
used are also highly toxic and not easily removed. To overcome these problems,
scientists at the Institute of Bio-engineering and Nanotechnology first treat
the bone with mild solvents.

Reconstructing Neural Circuits in 3D, Nanometer by Nanometer. The authors'
custom-designed microtome holds the tissue block in a way that ensures image
alignment and maintains focus; all the while the specimen surface is positioned
close enough to the objective lens to allow high-resolution imaging. Denk and
Horstmann expect that with this method they might ultimately be able to cut
sections thinner than the 50 nanometers that their current setup manages. This
then would allow them to cut sections even thinner than what is routinely
possible in conventional transmission electron microscopy. While the authors
doubt that the lateral resolution will ever reach that of transmission electron
microscopy, they also argue that such high resolution may not actually be needed
to trace neuronal connectivity. On the other hand, the method accelerates 3D
electron microscopic data collection "by several orders of magnitude" by
obviating the need for the labor-intensive adjustments to correct alignment and
distortion required by other methods, an advance that is crucial for

The National Cancer Institute (NCI) announced today at a media briefing a new
$144.3 million, five-year initiative to develop and apply nanotechnology to
cancer. Nanotechnology, the development and engineering of devices so small that
they are measured on a molecular scale, has already demonstrated promising
results in cancer research and treatment. "Nanotechnology has the potential to
radically increase our options for prevention, diagnosis, and treatment of
cancer," said Andrew von Eschenbach, M.D., director of the National Cancer
Institute. "NCI's commitment to this cancer initiative comes at a critical time.
Nanotechnology supports and expands the scientific advances in genomics and
proteomics and builds on our understanding of the molecular underpinnings of
cancer. These are the pillars which will support progress in cancer."

Tumbleweeds in the Bloodstream. Molecule-size sensors inside astronauts' cells
could warn of health impacts from space radiation. Wouldn't it be nice if the
cells in your body would simply tell you when you're starting to get sick, long
before symptoms appear? Or alert you when a tumor is growing, while it's still
microscopic and harmless? The ability to detect changes inside of individual
cells while those cells are still inside your body would be a boon to medicine.
NASA-supported scientists are developing a technology right now that could, if
it works, do exactly that. (Yubanet 10/30/04)

It's time for an alternative fuel. The era of human development with oil and gas
as energy source is nearing its end and in the next 30-40 years, there will be a
'clean break' to produce energy from renewable, non-fossil fuels, mostly from
hydrogen. The rise in global temperature due to emission of green house gases
will force man to seek alternatives so that life is viable on earth, M S
Srinivasan, additional secretary, Union Ministry of Petroleum and Natural Gas,
said today... 'By combining nanotechnology manipulating subatomic particles for
new products and hydrogen for alternative fuel, a way can be found on how to
store hydrogen and discharge into the usage system,' he said. (Regionalfare

Drug-dispensing Contact Lens Developed. Could treat eye diseases better than
drops. Drug-loaded contact lenses have been developed that could treat eye
conditions such as glaucoma far more effectively than drops. Usually sufferers
of glaucoma and many other eye conditions are prescribed eye drops. These can
mix with tears, however, and drain into the nose where they enter the
bloodstream and cause side-effects. As well, drops are inconsistent and
difficult to regulate. Researchers from the Institute of Bioengineering and
Nanotechnology (IBN) in Singapore recognized this problem and have created a
contact lens material that can deliver drug treatments directly into the eye.

UCLA Chemists Report New Nano Phenomenon: Welding in Response to an Ordinary
Camera Flash. UCLA chemists report the discovery of a remarkable new nanoscale
phenomenon: An ordinary camera flash causes the instantaneous welding together
of nanofibers made of polyaniline, a unique synthetic polymer that can be made
in either a conducting or an insulating form. The discovery, which the chemists
call "flash welding," is published in the November issue of the journal Nature
Materials..."I was very surprised," Kaner said. "My graduate student, Jiaxing
Huang, decided to take some pictures of his polyaniline nanofibers one evening
when he heard a distinct popping sound and smelled burning plastic. Jiaxing
recalled a paper that we had discussed during a group meeting reporting that
carbon nanotubes burned up in response to a camera flash. By adjusting the
distance of the camera flash to his material, he was able to produce smooth
films with no burning, making this new discovery potentially useful." (UCLA

ASU Biodesign Researcher to Explore Revolutionary Gene Sequencing: Threading the
Molecular Needle. A radical new method of DNA sequencing currently being
explored by Stuart Lindsay, Director of the Center for Single Molecule
Biophysics in the Biodesign Institute at Arizona State University and Professor
of Physics at ASU, could make the long-dreamt-of era of true genetic medicine
possible with extremely rapid, accurate and low cost sequencing of single DNA
molecules...Lindsay's new sequencing technology involves using Atomic Force
Microscopy (AFM), which is customarily used to analyze the surface structure of
materials at molecular resolution with the ultra-small tip of a sensitive
probe, in combination with naturally occurring ring-shaped sugar molecules
called cyclodextrins. Lindsay believes that the ring molecules, when paired with
the AFM probe tip, can effectively be used as sensors to "read" the sequence of
amino acid code (DNA "bases") in the human genome that comprises many millions
of bases. (ASU 10/29/04)

Doing More with Less. A new way to learn how large proteins move. In a development that will help scientists better determine how many large proteins work, Berkeley Lab's Paul Adams and collaborators used the latest advances in computational analysis to study how a complex biological machine refolds proteins, a process critical to cell survival. They took advantage of the fact that the protein, called a chaperonin, encapsulates unfolded proteins by moving large portions of its structure in unison, like a hand clenching a marble. This means that only a few frames of crystallographic images, each revealing the protein at a different stage of its motion, are needed to picture the entire process.

Nanotubes form along atomic steps. The Weizmann Institute of Science today announced that a research group headed by Dr. Ernesto Joselevich has developed a new approach to create patterns of carbon nanotubes by formation along atomic steps on sapphire surfaces. Carbon nanotubes are excellent candidates for the production of nanoelectronic circuits, but their assembly into ordered arrays remains a major obstacle toward this application. (Eurekalert 12/21/04)

Winning an Uphill Battle. It sounds as unlikely as toothpaste flowing back into the tube: A simple hole in a cell membrane can cause glycerol to flow "uphill," out of the cell, when the higher concentration outside would ordinarily make it flow the other way. Known as a channel protein, the molecular hatch acts like a ratchet to squeeze one glycerol molecule after another in the direction opposite the concentration gradient, researchers calculate in the 3 December PRL. Cells may use this effect to avoid overdosing on glycerol. (Physicsweb 12/3/04)

NNI has inspired or at least encouraged 40 similar programs. Most importantly,
it has fostered true collaboration among the 22 participating government

to order the guests on the interior of our large free-standing capsules," he
says. "Second, and most remarkably, we show that these large capsules
communicate with each other, at least in the solid state and probably in
solution, by the formation of intercapsule hydrogen bonds. This communication in
turn leads to a completely different ordering of the guests within the
capsules." (C&Enews 2/3/05)

New look for nanomotors. Physicists in the US have built the first
nanoelectromechanical device that exploits the effects of surface tension. The
"relaxation oscillator" consists of two droplets of liquid metal on a substrate
made of carbon nanotubes and can be controlled with a small applied electric
field. Alex Zettl and colleagues at the University of California at Berkeley and
the Lawrence Berkeley National Laboratory say the device could find use in
various nanomechanical applications, including actuators and motors (B C Regan

Hold Still. Particles floating in a fluid jiggle constantly, an effect called
Brownian motion, which makes them tricky to handle. A new trapping technique,
described in the 25 March PRL, effectively cancels out the Brownian motion of a

could allow researchers to hold and manipulate smaller particles than they can
with current techniques and could help them fabricate nanomachines or hold
biomolecules in place while their interactions are monitored. (PRF 4/25/05)

Smart Nanocarriers to Combat Tumors. IBN's technology spells hope for cancer
patients who suffer from painful side-effects of chemotherapy. A 'smart'
nanocarrier technology developed by a team of researchers at the Institute of
Bioengineering and Nanotechnology (IBN) is set to vastly improve the way cancer
patients are treated. Anticancer drugs are now being administered to patients
using methods that cause the indiscriminate killing of both diseased and healthy
cells. Such chemotherapy leads to side-effects, such as nausea, fatigue, and
hair loss, and makes the patient weak and frail. Between 1998 and 2002, 38,447
people in Singapore were diagnosed with some type of cancer, while 20,289 died
of the disease. Hence, there is a crucial need for the development of more
effective cancer therapy, which not only minimizes side-effects but also
directly targets diseased cells. Scientists at IBN have found a way to tackle
this problem through the use of anticancer drug delivery vehicles that transport
drugs only to where they are needed in the body. This method significantly
reduces or even eliminates the severe side-effects typically induced by
conventional chemotherapeutics. (AStar 3/21/05)

Human Contact Spreads PC Viruses. The federal Centers for Disease Control (CDC) and National Science Foundation (NSF) have issued a stunning joint announcement: PC viruses, worms, and spyware can now be transmitted via human contact. Researchers at St. Paul's College in Virginia have isolated roughly 100 cases of systems infected by human contact, the two agencies said at a press conference at NSF headquarters in Arlington, Virginia. The mode of transmission? Each system's user had physical contact with another user whose system was known to be infected. The level of contact was found to be as brief as a handshake. One researcher, Avril Hidokwon, said she documented a case where the Netsky.P virus spread to 12 systems via a sneeze. Scientists have long held that electronic viruses could not possibly spread unless there was some sort of digital (wired or wireless) connection between the infected PC and the victim systems (or the victim systems and servers). "What we did not account for," explained Hidokwon at the hastily organized joint press conference, "was nanotechnology." (PCmag 4/1/05) http://www.pcmag.com...,1781208,00.asp

A V6 Engine for the Nano-Age. The world of the very small is about to receive a very powerful engine. Berkeley Lab scientists have created the world's smallest electric motor that may someday power nanoscale devices that walk, crawl, swim, and fly. Although it is too early too determine what the motor will propel - perhaps probes that deliver disease-fighting drugs inside the body or winging nanobots that sniff out explosives - it packs a big kick in its tiny frame. The motor measures only 200 nanometers long (a nanometer is one-billionth of a meter), but its power density is 100 million times greater than that of a 225-horsepower V6 engine. It draws its enormous power from surface tension, the same cohesive force between liquid molecules that allows bubbles to form and insects to walk on water.

Tiny Bundles Seek And Destroy Breast Cancer Cells. A Penn State College of Medicine study shows for the first time in an animal model that ceramide, a naturally occurring substance that prevents the growth of cells, can be administered through the blood stream to target and kill cancer cells. "Ceramide is the substance that accumulates in cancer tissues and helps to kill cancer cells when patients undergo chemotherapy and radiation," said Mark Kester, professor of pharmacology, Penn State College of Medicine, Penn State Milton S. Hershey Medical Center. "By boosting the amount of ceramide through an injection in the bloodstream, our study in mice suggests that we can provide a stronger cancer-killing therapy without additional side effects." This study, titled "Systemic Delivery of Liposomal Short-Chain Ceramide Limits Solid Tumor Growth in Murine Models of Breast Adenocarcinoma," was published in the May issue of Clinical Cancer Research, a journal of the American Association for Cancer Research.

Nanotech Finds Tumors Before Visible on MRI. Biomedical engineers have used nanotechnology to find human melanoma tumors in mice while the growths are still invisible to conventional magnetic resonance imaging (MRI). Earlier detection can potentially increase the effectiveness of treatment. This is especially true with melanoma, which begins as a highly curable disorder, then progresses into an aggressive and deadly disease. A second benefit of the approach is that the same nanoparticles used to find the tumors could potentially deliver stronger doses of anti-cancer drugs directly to the tumor site with fewer side effects.

>From attograms to Daltons: Cornell NEMS device detects the mass of a single DNA molecule. Some people are never satisfied. First, nanotechnology researchers at Cornell University built a device so sensitive it could detect the mass of a single bacterium--about 665 femtograms. Then they built one that could sense the presence of a single virus -- about 1.5 femtograms. Now, with a refined technique, they have detected a single DNA molecule, weighing in at 995,000 Daltons -- a shade more than 1 attogram -- and can even count the number of DNA molecules attached to a single receptor by noting the difference in mass. The devices, which fall in the class of nanoelectromechanical systems (NEMS), could be made even more sensitive through increased miniaturization, the researchers say. The technology, they suggest, can be combined with microfluidics to perform genetic analysis of very small samples of DNA, even the amount present in a single cell.

Nanotube water doesn't freeze - even at hundreds of degrees below zero. A new form of water has been discovered by physicists in Argonne's Intense Pulsed Neutron Source (IPNS) Division. Called nanotube water, these molecules contain two hydrogen atoms and one oxygen atom but do not turn into ice - even at temperatures near absolute zero. Instead, inside a single wall tube of carbon atoms less than 2 nanometers, or 2 billionths of a meter wide, the water forms an icy, inner wall of water molecules with a chain of liquid-like water molecules flowing through the center. This occurs at 8 Kelvins, which is minus 445 Fahrenheit. As the temperature rises closer to room temperature, the nanotube water gradually becomes liquid.

World's most precise "hard x-ray" nanoprobe activated. Marking a
major step forward in using x-rays to study extremely small
structures and phenomena, the world's first "hard x-ray" nanoprobe
beamline was activated on March 15, 2005. The unique nanoprobe is
one of the featured instruments at the new Center for Nanoscale
Materials (CNM), a U.S. Department of Energy user research facility
located at Argonne National Laboratory, about 25 miles west of
Chicago. CNM researchers expect to soon be using the x-ray nanoprobe
to study individual atoms, molecules, and the unique physical
interactions that occur at the nanoscale, where features are
measured in nanometers, or billionths of a meter (a nanometer is
70,000 times smaller than the width of a human hair). (Nanoapex

risks" of nanotechnology, DuPont CEO Chad Holliday and Environmental
Defense (ED) President Fred Krupp are calling for "increased risk
research, improved regulatory oversight, proactive corporate
management standards, and broad stakeholder engagement." Given
potential liability and market risks, industry, universities,
government and public interest groups should collaborate to
determine what testing is necessary for new nanoproducts. Businesses
then should conduct the needed testing before new products enter
commercial use. . . A collaborative effort could set interim
standards for nanotechnology around the world while regulations are

Nanowires In Blood Vessels May Help Monitor, Stimulate Neurons In The Brain.
Working with platinum nanowires 100 times thinner than a human hair--and using
blood vessels as conduits to guide the wires--a team of U.S. and Japanese
researchers has demonstrated a technique that may one day allow doctors to
monitor individual brain cells and perhaps provide new treatments for
neurological diseases such as Parkinson's. Writing in the July 5, 2005, online
issue of The Journal of Nanoparticle Research, the researchers explain it is
becoming feasible to create nanowires far thinner than even the tiniest
capillary vessels. That means nanowires could, in principle, be threaded through
the circulatory system to any point in the body without blocking the normal flow
of blood or interfering with the exchange of gasses and nutrients through the
blood-vessel walls. (ScienceDaily 7/19/05)

Nano-surgeons break the atomic bond. The science of the small has moved a huge
step forward following work in a subterranean Birmingham laboratory, reports
Roger Highfield. The ultimate in surgery has been carried out in a
vibration-free bunker in deepest Birmingham. Not only have scientists working
there managed to remove a single atom of matter, measuring about a tenth of a
millionth of a millimetre across, but they have achieved this feat even though
their subject was thrashing around wildly. The feat is the ultimate in the
science of the small, nanotechnology, that the practitioners hope will one day
help to remove contaminants from the environment. One can also see it as an
extreme version of precision chemistry, a far cry from what usually happens in a

2005, the first nanoparticulate drug delivery product, Abraxane for the
treatment of breast cancer was launched by Abraxis Oncology, a division of
American Pharmaceutical Partners, Inc. The initial announcement in late 2004 saw
the company's share prices rise by 50% and required the Food and Drug
Administration (FDA) to create a new class of therapeutic products. Operating at
scales of billionths of a metre, nanoparticle drug delivery systems involve
binding a therapeutic compound to a nanoparticle, or encasing it within a
nanoshell. Common materials in development include gold or silicon
nanoparticles, with the Abraxane system using a nanoparticle shell constructed
from albumin. A key advantage of nanoshells is that they can be targeted to
specific cell populations through conjugation with a monoclonal antibody.

The market for the instruments and tools needed to work on the nanoscale faces
substantial challenges in the future, experts told UPI's Nano World.
Atomic-force microscopes, or AFMs, and other tools that experiment on carbon
nanotubes and other areas outside the semiconductor industry "are the things
that make nanotechnology possible to begin with," said Nathan Tinker, co-founder
and executive vice president of the NanoBusiness Alliance in New York City."They
represent the state of the art, and the ability for nanotechnology to drive
forward institutionally across industrial sectors."Nanotech analysis group Lux
Research, also in New York, has estimated the global impact of nanotech-enabled
goods at $2.6 trillion by 2015...Still, the costs for ramping up the mostly
research-oriented tools used to work on the nanoscale to large-scale production
processes are going to be substantial, Tinker said.Moreover, this ramping up is
only a fraction of the challenge ahead. "The big problem seems to me in getting
these machines to the point of reliability needed at an industrial scale," he
said." (PhysOrg 7/22/05) http://www.physorg.com/news5379.html
