Abstract:

Inorganic nano-metal oxides may be efficient replacements for organic antibiotics that are drug-resistant due to their wide range antibacterial activity towards pathogenic and mutagenic bacterial species. In this work, zinc and copper oxide nanoparticles were produced using Catharanthus roseus flower extract. It is a feasible alternative to other techniques because the biosynthesized nanomaterials made from plant extract are non-toxic and harmless to the environment. The X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-Vis, and Fourier transform infrared spectrometry (FT-IR) investigations were achieved to confirm CuO and ZnO nanoparticles produced. In the DPPH experiment, the antioxidant properties of CuO and ZnO nanoparticles performed well. Gram-positive and gram-negative microorganisms are both effectively combatted by the produced copper and zinc oxide nanoparticles. The findings suggest that CuO nanoparticles were more effective towards microorganisms than ZnO nanoparticles.
