Abstract: Green grape seed extract was used to create copper oxide (CuO) nanoparticles as an environmentally acceptable stabilising and reducing agent. When copper sulphate pentahydrate was reduced with sodium hydroxide (NaOH), the colour changed from blue to greenish-black, indicating that the pH had been corrected to 9. Functional groups including O-H stretching and metal-oxygen bonding were validated by FTIR analysis, confirming the creation of nanoparticles. Absorbance peaks at 372.75 nm and 390.05 nm were visible in UV-Vis spectroscopy, emphasising electronic transitions and charge transfer. X-ray diffraction (XRD) verified a monoclinic crystal structure with a crystallite size of 30.55 nm, while dynamic light scattering (DLS) showed an average particle size of 181.6 nm with a Polydispersity Index of 0.185. The CuO nanoparticles exhibited notable antibacterial activity, exhibiting 40 mm, 42 mm, and 43 mm inhibitory zones.
