Synthesis and antimicrobial activities of Manganese (Mn) and iron (Fe) co-doped Cerium dioxide (CeO2) Nanoparticles

Cerium oxide (CeO2) nanoparticles (also called nanoceria) have broad range of applications in various fields, especially in the biomedical sector. Doping of CeO2with different elements can vary the optical, structural, biomedical and electrical characteristics of cerium dioxide nanoparticles. In this study CeO2was doped with different concentrations of Manganese (Mn) and Iron (Fe). The characterization techniques used for analysis of CeO2nanoparticles were X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and I–V analysis. The particles were also tested for Antibacterial and Antifungal activity. For antibacterial activity test, gram-positive test was conducted by Staphylococcus aureus and gram-negative tested on E. coli. The antifungal activity was tested with Candida Albicans.
