Bioengineered cerium oxide (CeO2) nanoparticles and their diverse applications: a review

Cerium oxide nanoparticles (CeO2 NPs) have received immense interest due to their wide application in environmental remediation, photocatalytic dye degradation, biological applications, and industrial fields. The environmental concerns and energy issues encourage the development of a green protocol to synthesize CeO2 NPs. The greener approach proffers environment-friendly, non-toxic, economically affordable, and efficient. This review describes: (1) the plant extracts, microbes, biological product mediated synthesis of CeO2 NPs, and the mechanism involved in manufacturing it, (2) photocatalytic dye degradation ability of CeO2 NPs; and (3) potential biological application as an antibacterial agent, antifungal activity, antioxidant activity, antidiabetic, and anticancer property. We believe this review will provide a handy guide to the researcher interested in the biosynthesis of CeO2 NPs and their possible applications.
