Size-Dependent Cytotoxicity and Reactive Oxygen Species of Cerium Oxide Nanoparticles in Human Retinal Pigment Epithelia Cells source:DovepressNanomaterials have unique properties, such as small size and enlarged surface area, that enhance regenerative and catalytic enzyme activities and, consequently, their biological effects. Cerium (Ce), a critical rare earth element with a unique f-electron configuration that gives its compounds special properties, has been called a universal new material.1 In cerium oxide nanoparticles (CeO2 NPs), there are two valence states-Ce3+ (reduced state) and...
