Preparation Of Cerium Dioxide Nps And Its Adoption In Biomedical Applications

Abstract

     A simple chemical approach was used to synthesize cerium dioxide (CeO₂) NPss (NPs). UV-Visible , (FTIR), (XRD) and (SEM) were used to characterize the CeO₂ NPs. It was found that band gap of the CeO₂ NPs (E_g = 4.1 electron volt) was enlarged as compared to bulk ceria (E_g = 3.19 electron volt) based on UV-Vis analysis. SEM scans indicated spherical-shaped particles with a diameter of 47.68 nm, which were verified by FTIR data at 594 cm-¹. Additionally, the generated CeO2NPs' antibacterial and antifungal efficacies were assessed, and the results showed that CeO₂ NPs had both antibacterial and antifungal activity. Activities had varied values because the two groups' cell walls and membranes had distinct compositions.
