In this study, a comparison was made between nanoparticles specifically copper oxide CuO prepared by two plasma methods, where the nanoparticles were prepared by pulsed laser ablation in a deionized liquid, and on the other hand, the nanoparticles were manufactured in the form of thin films deposited on a glass substrate where the material was evaporated in a vacuum chamber by laser. In both cases, a Nd:YAG laser was used with a wavelength of 1064 nm, and a frequency of 6 Hz. Some tests were performed on the nanoparticles such as X-ray diffraction (XRD) to study the crystal structure of the samples, as well as scanning electron microscopy (FESEM) to study the morphology of the samples and particle sizes, and optical properties (UV-VIS) to study the absorption and optical energy gaps. The samples were also tested to determine their effectiveness and use as an inhibitor of bacteria at different dilution concentrations.
