Determination of Antimicrobial Activity of Copper Oxide Nanoparticles| Chapter 11 | Recent Trends in Chemical and Material Sciences Vol.6

Summary: Research into the antibacterial properties of copper oxide nanoparticles (CuO NPs) is gaining traction. CuO NPs produced using a simple precipitation process were studied for structural and antibacterial characteristics. As a precursor, copper (II) acetate was employed, and sodium hydroxide was used as a reducing agent. The crystalline structure of CuO NPs was shown by the X-ray diffraction pattern (XRD). CuO NPs were studied using a field emission scanning electron microscope (FESEM) and a field emission transmission electron microscope (FETEM). CuO NPs had an average diameter of roughly 23 nm as measured by TEM and XRD. The XRD pattern and energy dispersive X-ray spectroscopy (EDS) spectrum indicated that the CuO NPs were very pure. CuO NPs were found to have outstanding antibacterial efficacy against a variety of bacterial species (Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Enterococcus faecalis, Shigella flexneri, Salmonella typhimurium, Proteus vulgaris and Staphylococcus aureus). Furthermore, E. coli and E. faecalis were the bacteria with the highest sensitivity to CuO NPs, while K. pneumonia was the bacteria with the lowest sensitivity. This finding calls for more research into the antibacterial activity of CuO NPs in a variety of different bacteria strains found in medical devices.
