Carbon Fullerenes shortly called as C60 Fullerenes are closed hollow shaped cages that consist of carbon atoms interconnected in hexagonal and pentagonal rings. The carbon atoms present on the cage surface are arranged in such a way that each atom is bonded to three neighbors and is sp2 hybridized. Generally, this Carbon Fullerenes C60 comes in the form of granular, dark-brown powder. It has a sublimed look as thick blue-black needle-like crystals reaching 5 to 8 mm. Films that are thinner than 5 microns are of golden-brown colour and has an outer diameter of about 1 nm. Fullerenes are the third allotropic form of carbon material after diamond and graphite. These were discovered in the year 1985. This C60 Fullerenes consist of twenty hexagonal and twelve pentagonal rings as the basis of an icosohedral symmetry closed cage structure. However, there is no scientific evidence indicating this carbon Fullerenes C60 is safe for human consumption. You can buy C60 Fullerenes at http://mstnano.com/products/fullerenes/.
Carbon Fullerenes C60 is isolated by proprietary methods from the extract that is a blend of carbon soot produced by a carbon arc operated under a sub-atmospheric helium environment. To indicate the presence of all fullerenes including parent oxides, HPLC analysis is included with the sample. These samples are vacuum-dried to remove any residual solvent present in it. Usually, the hydrocarbon content is less than 0.5 percent in this C60 Fullerenes. Thin films and lure sublimed crystalline powders ensure that each and every purity requirement is met for solid-state research. The hydrocarbon content is typically less the 0.01 percent.

This Fullerenes 60 is not “super aromatic” as it tends to avoid double bonds in the pentagonal rings, resulting in poor electron delocalisation and due to this very reason C 60 behaves like an electron deficient alkenes and reacts readily with electron rich species. The C60 and C70 Fullerenes can be used in just the same way as an organic photovoltaics, which is the strong antioxidants, that reacts quickly and at a high rate with free radicals and are often the cause of cell death or damage.
The Carbon Fullerenes 60 molecule consists of two bond lengths, the 6:6 ring bonds can be considered as the double bonds and they are a little shorter than the 6:5 bonds. The electronic bonding and geodesic factors in the C 60 structure account for the overall stability aspect which is very crucial to the molecule.
