Abstract: In recent ages, green nanotechnology has gained attraction in the synthesis of metallic nanoparticles due to their cost-effectiveness, simple preparation steps, and environmentally- friendly. In the present study, copper oxide nanoparticles (CuO NPs) were prepared using Nigella sativa leaf extract as a reducing, stabilizing, and capping agent. Bioactive copper nanomaterials are an emerging class of nano-antimicrobials providing complimentary effects and characteristics, as compared to other nano-sized copper oxide metal. The CuO NPs were characterized via UV–Vis Spectroscopy. The UV–Vis spectra of CuO NPs showed a surface plasmonic resonance band to occur at 851 nm. Furthermore, as-formed CuO NPs shown strong antibacterial activity against the Gram-positive bacteria (Bacillus Cereus, Bacillus Substillus), and Gram-negative bacteria (Pseudomonas Aureginosa, Salmonella Typhimurium, Enterobacter Aerogenus). According to the results of this investigation, green synthesized CuO NPs with Nigella sativa leaf extract may be used in biomedicine as a replacement agent for biological applications.
