Green Synthesis, Characterization and Antimicrobial Activity of Copper Oxide Nanoparticles

Abstract

The objective of this study was to examine the impact of biologically produced CuO-NPs (Copper oxide nanoparticles) on the growth of bacterial strains. The physico-chemical properties of CuO-NPs were analyzed using a UV-Vis spectrophotometer, X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), and energy-dispersive X-ray spectroscopy (EDS). The disc plate diffusion experiment was employed to assess the antibacterial efficacy of CuNPs. The work has demonstrated the potential antibacterial effects of CuO-NPs generated through biological means. These effects were observed at various doses, ranging from 10 to 100 µg/ml, against Escherichia coli and Staphylococcus aureus germs. Nanoparticles, or NPs, are particles with sizes ranging from 1 to 100 nm. These particles exhibit enhanced physical and chemical capabilities as a result of their large surface area. The current study demonstrates the potential use of biosynthesized CuO NPs for treating bacterial infectious diseases in the near future.
