Green synthesis of cerium oxide nanoparticles using Citrus nobilis Lour. Peel extract and evaluation of their potential as antibacterial and antioxidant agents
Cerium oxide nanoparticles (CeO 2 NPs) 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 CeO 2 NPs. Scanning electron microscope (SEM) and Transmission electron microscope (TEM) revealed that CeO 2 NPs 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 CeO 2 NPs were highly effective against S.aureus bacteria demonstrating their potential for biomedical applications.
