Synthesis and Characterization of Cerium Oxide Nanoparticles using Curvularia lunata and Their Antibacterial properties
نویسندگان
چکیده
In the present work, we have investigated synthesis of cerium oxide nanoparticles (CeO2 NPs) using Curvularia lunata culture filtrate. The synthesized CeO2 NPs were characterized by TG/DTA, XRD, Raman, PL, FTIR, UV-visible spectroscopy and TEM analyses. The synthesized nanoparticles retained the cubic structure, which was confirmed by X-ray diffraction studies. UV-visible spectrum exhibited a well defined absorption peak at 298.35 nm.. TEM images showed that the NPs possessed spherical shape and particle size range from 5 to 20 nm. Application of the synthesized CeO2 NPs was investigated by antibacterial activity, which shows a significant inhibition towards both gram positive and gram negative bacteria. KeywordsCurvularia lunata, CeO2 NPs, Raman spectroscopy, TEM, Antibacterial activity
