First drawing out blood (either human or mice) and then using Microinjection techniques to insert C60oo directly inside blood cells to see if they live any longer (under culture), if they look any different under the microscope, or if they behave differently under cellular tests and chemicals.
Then such microinjected blood can be injected back in the body to see if they trigger a (hopefully positive) chain reaction.
So far it ain't clear if oral C60oo stays inside cells so microinjections can bypass or hasten up cell transport/diffusion issues.
It makes it also possible to directly deliver C60 to specific parts of the cell like the nucleus and mitochondria.
Equipment is expensive for DIYers so its better left for those with access to existing labs.
