The protective effect of Dex-CeNP against hydrogen peroxide induced oxidative damage in cells. A) Schematic showing cerium oxide nanoparticles neutralizing hydroxyl free radicals via an oxidation-reduction cycle. Dex-CeNP protected B) C2BBe1 and C) BJ5ta cells from hydrogen peroxide exposure (0.075% and 0.0125%, respectively). Data presented as mean ± SD. Three independent experiments were performed (n=3). ** indicates statistically significant difference at p < 0.01.
