Rare Earths and Nanotechnology
Nanoparticles Explored for Preventing Cell Damage
By Cecile Gonzalez , National Science Foundation posted: 26 June 2009 08:24 am ET This Behind the Scenes article was provided to LiveScience in partnership with the National Science Foundation. Sudipta Seal is enthralled by nanoparticles, particularly those of a rare earth metal called cerium. The particles are showing potential for a wide range of applications, from medicine to energy. Seal is a professor of materials science and engineering at the University of Central Florida (UCF), and several years ago he and his colleagues engineered nanoparticles of cerium oxide (CeO2), a material long used in ceramics, catalysts and fuel cells. The novel nanocrystalline form is non-toxic and biocompatible — ideal for medical applications. Since then, the researchers found that cerium oxide nanoparticles have two additional medical benefits: they behave like an antioxidant, protecting cells from oxidative stress, and they can be fine tuned to potentially deliver medical treatments directly into cells.
