Cerium Oxide Nanoparticles: Synthesis, Characterization and Study of Antimicrobial Activity

Cerium Oxide Nanoparticles: Synthesis, Characterization and Study of Antimicrobial Activity

Cerium an element in lanthanide series exhibit both oxidation state Ce3+ and Ce4+ and as ability to drastically adjust or to switch over its oxidation state easily. Cerium oxide nanoparticles with 20 - 100nm in diameter were synthesized via hydroxide mediated approach using surfactants. Different surfactants such as sodium dodecyl sulphate (SDS) and cetyl trimethyl ammonium bromide (CTAB) possess the ability to control the shape and size of cerium oxide nanoparticles synthesized by using cerium nitrate hexahydrate as the starting material via hydroxide mediated approach. Cerium oxide nanoparticles were coated using polyvinyl pyrrolidine (PVP) as the polymer. The structural and morphological studies of cerium oxide nanoparticles were characterized by scanning electron microscopy. The antibacterial activities of nanoceria were studied with respect to Gram positive bacteria and Gram negative bacteria by disc diffusion method.
