Antioxidant Activity

Results published in 1999 have shown that fullerenes have a potential as biological antioxidants. The antioxidant property is based on the fact that fullerenes possess large amount of conjugated double bonds and low lying lowest unoccupied molecular orbital (LUMO) which can easily take up an electron, making an attack of radical species highly possible. It has been reported that up to 34 methyl radicals have been added onto a single C60 molecule. This quenching process appears to be catalytic. In other words, the fullerene can react with many superoxides without being consumed. Due to this feature fullerenes are considered to be the world’s most efficient radical scavenger and are described as radical sponges (Krusic et al 1991).
