Nano-antioxidants prove their potential

Rice-led study shows how particles quench damaging superoxides

Polyethylene Glycol-Hydrophilic Carbon Cluster
A polyethylene glycol-hydrophilic carbon cluster developed at Rice University has the potential to quench the overexpression of damaging superoxides through the catalytic turnover of that can harm biological functions.
