Effect of Zn Doping on Antibacterial Efficacy of CuO Nanostructures

Abstract Bacterial diseases are causing major health issues across the world. Recent research has revealed that the metal ion discharge of nanomaterials is extremely effective at eradicating bacterial outbreaks and resistance. Reactive oxygen species (ROS) for antibacterial functions have been produced using nanomaterials with high specific surface area, complex structural framework, and spectral properties. In this study, we thoroughly investigated the impact of Zn dopants on copper oxide (CuO) nanostructures and their nanomaterial‐based antibacterial processes. The method of production includes the formation of CuO and Zn‐doped CuO nanostructures via chemical coprecipitation. By using several characterization techniques, the as‐synthesized nanostructures were confirmed. Based on their specific surface area and surface‐active site, the different antibacterial activities of these dopants vary the antibacterial action. The antibacterial activity was evaluated using the agar well diffusion method. A significant antibacterial action was observed in the samples. In the pharmaceutical and food sectors, this CuO and its combined dopants can be a substitute for synthetic antibacterial agents.
