Could nanoparticles be designed to become potent antioxidants?

Abstract:
The responses of cells exposed to nanoparticles have been studied with regard to toxicity, but very little attention has been paid to the possibility that some types of particles can protect cells from various forms of lethal stress.

Research at the Salk Institute for Biological Studies and Columbia University now shows that nanoparticles composed of cerium oxide or yttrium oxide protect nerve cells from oxidative stress and that the neuroprotection is independent of particle size.
