"Regenerative catalytic rare earth nanoparticles as therapeutics"
Prof. Sudipta Seal
University of Central Florida

We have merged nanoscale engineering with cell biology to potentially intervene in a common biomedical pathology, ranging from aging to free radical-induced cell dysfunction. Using a simple wet chemical synthesis method, we have successfully created biocompatible ceria nanoparticles (NPs) with or without dopants. For the first time, we have observed that the oxidation state of cerium changes with the environment and time, subsequently affecting the variation in the absorption edge. These environmentally induced changes in the band edge are likely to contribute to inconsistencies regarding quantum confinement effects for nanoceria reported in the literature.
