Synthesis and characterization of highly efficacious Fe-doped ceria nanoparticles for cytotoxic and antifungal activity

Ceria nanoparticles (NPs) are promising materials for their superior anticancer and antifungal activities. In this work, we synthesized Fe-doped ceria NPs by co-precipitation method using xanthan gum (XG) as a green capping agent. The NPs were calcined at different temperatures ranging from 200 to 800 °C. The crystallinity, crystallite size, structure, particle size, morphology, and magnetic property of the NPs were investigated by using x-ray diffraction, field emission scanning electron microscopy, vibrating sample magnetization, Fourier transform infrared spectroscopy, and dynamic light scattering. The influence of calcination temperature on the crystallite size was critically examined. The crystallize size of the Fe-doped ceria NPs was dependent on the calcination process and increased with increasing temperature. Nanocrystalline ceria particles with spherical morphology was…
