Abstract: Cerium dioxide (CeO₂), also known as ceric oxide, ceric dioxide, ceria, or cerium oxide, is a rare-earth metal oxide that functions as an n-type semiconductor with a band gap of approximately 2.9 eV. It has attracted considerable attention due to its unique band characteristics, remarkable adsorption capacity, radiation stability, and versatile surface chemistry. The exceptional durability, biocompatibility, and reactivity of cerium oxide nanoparticles (CeO₂ NPs) further enhance their importance in advanced research and technological applications. Owing to these properties, CeO₂ NPs are extensively explored across diverse fields such as agriculture, medicine, sensing devices, cellular systems, and targeted drug delivery. Their high reactivity and distinctive physicochemical behavior make them promising candidates for agricultural applications, contributing to improved ecological balance and food productivity. Their proven biocompatibility, as evidenced by both in vitro and in vivo studies, supports their utilization in biomedical applications. This review highlights various synthesis approaches and discusses the advancement of cerium dioxide nanoparticles.
