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.

氧化铈（CeO ₂）纳米颗粒（也称为纳米氧化铈）在各个领域，尤其是在生物医学领域中具有广泛的应用。用不同元素掺杂CeO ₂可以改变二氧化铈纳米颗粒的光学，结构，生物医学和电学特性。在这项研究中，CeO ₂掺杂了不同浓度的锰（Mn）和铁（Fe）。用于分析CeO ₂纳米粒子的表征技术是X射线衍射（XRD），傅立叶变换红外光谱（FTIR）和IV分析。还测试了颗粒的抗菌和抗真菌活性。为了进行抗菌活性测试，金黄色葡萄球菌进行了革兰氏阳性测试和革兰氏阴性在大肠杆菌上测试。用白色念珠菌测试抗真菌活性。
