Potent antioxidants designed by nanotechnology

Abstract:
There has been a great deal of interest in the toxicity of nanoparticles in the context of respiratory health. 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 has shown that nanoparticles composed of cerium oxide or yttrium oxide protect nerve cells from oxidative stress and that the neuroprotection is independent of particle size. This has led researchers to the conclusion that there is a potential for engineering this group of nanoparticles for therapeutic purposes.
