Essentially, free radicals are unstable molecules that cause damage to cells around them in an attempt to restabilise themselves. When there are more free radicals in the body than natural and/or supplemental antioxidants, like C60, the body incurs oxidative stress.
C60, aka Buckminsterfullerene, bucky balls or the magic molecule, is a radiation resistant, nanotechnology. This tiny fella, the most symmetrical molecule in existence, is constructed of 60 pure carbon atoms; it has been found to occur naturally on Earth and in deep space, as well as being produced by humans. This might take you back to high school, but carbon is a building block of life itself.
A new reaction that shows C60 fullerene derivatives which effectively combat viral outbreaks, as well as HIV, herpes simplex virus and cytomegalovirus, has been discovered by a collaboration of scientists from the Skoltech Center for Energy, Science and Technology, the Institute of Problems of Chemical Physics of RAW and other foreign research centres.
