Green Syn Thesis and Biological Applications of Cerium Oxide Nanoparticles

Abstract

In the biological and medical sciences, CeO₂ nanoparticles (NPs) have demonstrated great potential as therapeutic agents. In the final interactions of the NP with target cells, the physicochemical characteristics of CeO₂-NPs, such as size, aggregation status in liquid, and surface charge, are crucial. Recently, CeO₂-NPs have been produced using a variety of bio-directed approaches using natural and organic matrices as stabilising agents in order to create biocompatible CeO₂-NPs, resolving safety concerns and creating the ideal environment for their successful application in biomedicine. The several green methods for creating CeO₂-NPs are covered in this review along with their benefits and difficulties. This review also emphasises current developments in the possible usage of CeO-NPs, which have superior redox characteristics in comparison to bulk materials. Additionally, the existence of a mixed valance state is crucial.
