Synthesis, Characterization and Antibacterial Activity of Cuo Nanoparticles

Abstract

Objective: The present study was done to see the effect of biologically synthesized CuO-NPs (Copperoxide nanoparticles) on the growth of bacterial strains.
 Methods: Physico-chemical characterization of CuO-NPs was done by UV-Vis-spectrophotometer, XRD, FE-SEM, and EDS. The disc plate diffusion assay was used to evaluate the anti-bacterial effect of CuNPs.
 Results: This study has shown a promising anti-bacterial activity of biosynthesized CuO-NPs at different concentrations ranging from 10 to 100 µg/ml against Escherichia coli and Staphylococcus aureus bacteria.
 Conclusion: Nanoparticles (NPs) are small size particles between range 1 to 100 nm which expand their physical and chemical properties due to high surface area. The present study reveals that there may be possible utilization of biosynthesized CuO NPs for the treatment of bacterial infectious disease in near future.

In-Situ Deposition of Metal Oxides Nanoparticles in Cellulose Derivative and Its Utilization for Wastewater Disinfection

“…Strong and sharp peaks appeared at 2θ of 28° (112) for cubic CuO crystallites. There are also three weak peaks at 2θ of 32°, 35.5° and 38.6° which are assigned to the (110), (002) and (111) crystal planes (JCPDS Card 033-0480) [ 45 , 46 ]. The crystal structure of the Acell was completely destroyed, due to the existing peak at 25.8 which shows a good correlation of the copper with the Acell.…”

Green synthesis of copper oxide nanoparticles using Spinacia oleracea leaf extract and evaluation of biological applications: Antioxidant, antibacterial, larvicidal and biosafety assay

“…Copper oxide particles prepared by the bio reduction process were analyzed regarding their size and chemical composition [33,34]. The initial detection of CuO NPs creation was witnessed by the colour change visually Using a UV-VIS spectrometer, CuO NPs were examined by UV-Vis Spectroscopy from 200 to 800 nm (HITACHI-U2800) [35]. The functional group present in the Green synthesized CuO NPs was founded by FT-IR spectrometer [36].…”

COVID-19 and a novel initiative to improve safety by 3D printing personal protective equipment parts from computed tomography

“…While zinc oxide nanoparticles have been shown to be cytotoxic, [ 58 ] there are antibacterial benefits [ 60 ]. Specifically, zinc oxide is an effective, and promising antiviral agent against the H1N1 influenza virus [ 61 ].…”
