Recently, the biosynthesis of metal oxide nanoparticles using plant extract gained great attention compared to other methods. In this work, CuO nanomaterial was synthesized by using the leaf extract of Solanum trilobatum. Synthesized copper oxide nanoparticles were characterized by UV, FT-IR, XRD, SEM, and EDX to determine the functional group, crystalline size, shape, and elemental composition of the synthesized nanoparticles. The X-ray diffraction and SEM results confirmed that the synthesized CuO NPs were crystalline in nature and the average size was found to be 38.34 nm. The spherical shape of CuO NPs was reported in the green approach, but first-time pentagons, cubes, and elongated forms of CuO NPs are found in this work. The EDX studies showed that the Solanum trilobatum mediated CuO NPs contain 53.57 % of copper and 46.43% of oxygen. Synthesized CuO NPs were tested against the five pathogenic bacteria and they showed a very good zone of inhibition compared with copper sulfate and plant extract. Especially against Escherichia Coli, Solanum trilobatum mediated CuO NPs performed well inhibitory effect.
