Nanoparticles to fight radiation

Abstract:
Fullerene is a carbon nanoparticle consisting of 60 carbon atoms (C-60) assembled into a spheroidal structure resembling a soccer ball. In 1997, scientists at the Washington University School of Medicine found that carboxyfullerenes, C-60 particles to which malonic acid groups are attached could effectively scavenge free radicals. They suggested that such fullerenes could be used as neuroprotectors against certain neurotoxic agents that cause neuronal death through the mediation of free radicals.

More recently, Dr Adam Dicker and colleagues of the Thomas Jefferson University at Philadelphia found that fullerene could act as an effective oxygen sink. That is, it can bind to oxygen free radicals and inactivate them.
