Abstract
Cerium oxide nanoparticles (CeO2NPs) have been synthesized using Siam oranges (Citrus nobilis Lour.) peel extract as a capping agent with varied concentration. X-ray diffraction (XRD) analysis confirmed the formation of cubic fluorite crystal structured CeO2NPs. Scanning electron microscope (SEM) and Transmission electron microscope (TEM) revealed that CeO2NPs were quasi-spherical with sizes ranging from 10 to 40 nm. The most optimum concentration of siam orange peel extract was 10 %. IC50 value of 70.55 mg mL−1 indicates a strong antioxidant activity of sample. Additionally, the antibacterial activity showed that CeO2NPs were highly effective against S.aureus bacteria demonstrating their potential for biomedical applications.
