Cerium Oxide Based Nanozymes

Abstract

Cerium oxide nanoparticles (nanoceria) are reported to exhibit nanozyme activities, such as biological catalase, oxidase, superoxide dismutase, and peroxidase-mimetic activities. Nanoceria nanozymesNanoceria nanozyme own several advantages over natural enzymes, such as controlled synthesis at low cost, tunable catalytic activities, as well as high stability against strict physiological conditions. Exploiting these properties, several biomedical applications, such as bio-sensing, immunoassay, drug delivery, radiation protection, and tissue engineering, have been exercised. This chapter provides a comprehensive summary of reported biological enzyme-mimeticBiological enzyme mimetics activities of nanoceria, the possible mechanismsCatalysis mechanism of catalysis, as well as their biomedical applications.
