ABSTRACT
In this paper we report the enzymatic properties of Ti-doped CeO(2) nanoparticles. The superoxide dismutase activity of Ti-doped nanoparticles is reduced in comparison to undoped nanoceria. In contrast, the oxidase activity of these nanoparticles was unchanged. The change in enzymatic activity was accompanied by a dramatic change in shape to a spherical nanostructure. In addition to reporting a new type of enzymatically-active nanoparticle, Ti-doped cerium oxide nanoparticles are well suited for biological applications.
