Synthesis and Antibacterial studies of Lanthanum, Cerium and Erbium loaded Copper Oxide Nanoparticles

Abstract

Field Emission Scanning Electron Microscopy (FESEM), X-ray Diffraction (XRD) and Energy Dispersive Spectra (EDS) were employed to synthesise and characterize Lanthanum, Cerium and Erbium loaded CuO nanoparticles (LCO, CCO and ECO NPs). The nanoparticles were explored for the antibacterial activity against the human pathogenic bacteria such as Salmonella typhimurium, Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumonia by the standard well diffusion method using amoxicillin as the standard. The nanoparticles exhibited excellent antibacterial activity against the growth of microorganisms. The Minimum Inhibitory Concentration (MIC) of the existing bacterial strains was also determined.
