Because of their potential applications in optoelectronics, nanoelectronics, sensors, catalysis, and information storage, metal oxide nanoparticles, or NPs, are the subject of much research. Using Mangifera indica leaf extract, the study sought to investigate the synthesis of CuO nanoparticles (NPs) and evaluate their properties. It was established whether Mangifera indica leaf extract was suitable for utilising a biological process in ambient conditions to produce copper oxide nanoparticles. The spherical-shaped CuO nanoparticles are polydisperse, with a range of particle sizes from 18 to 106 nm. 52.54 nm was the average size. Colour changes indicate the generation of CuO nanoparticles (NPs) through plasmon resonance with the bioactive compounds in the Mangifera indica leaf extract. FT-IR, UV-vis spectroscopy, XRD, EDX, and SEM methods were also used to confirm the presence of CuO nanoparticles. As a capping agent and aiding in the bio reduction process, the functional groups have been shown to have a probable affinity for copper oxide. This affinity is seen with alkynes, aromatics, phenol, and alcohol. The agar well diffusion method was used to evaluate the antibacterial effectiveness of the generated copper nanoparticles and to identify the lowest inhibitory concentration. The zone of inhibition could be anywhere between 10 and 30 mm in length. However, depending on the particular organism under investigation, the bactericidal effectiveness of copper nanoparticles varies.
