Abstract

Nanoceria is considered as a potent antioxidant (free radical scavenger) and its enzymatic activity is reported to be a function of the oxidation state of surface cerium ions. Here we demonstrate phosphine ligand-dependent enzymatic activity of nanoceria irrespective of its as-synthesized oxidation state.
