Abstract

Abstract: Bacterial has become a common pathogen of humans owing to their drug-resistant effects and evasion of the host immune system, with their ability to form biofilm and induce severe infections, a condition which has become a primary public health concern globally. Herein, we report on CuO@AgO/ZnO NPs antibacterial activity enhanced by near-infrared (NIR) light which was effective in the elimination of Staphylococcus aureus and the Pseudomonas aeruginosa . The CuO@AgO/ZnO NPs under NIR significantly eradicated S. aureus and its biofilm and P. aeruginosa in vitro, and subsequently exhibited such phenomenon in vivo, eliminating bacteria and healing wound. This demonstrated the combined intrinsic antibacterial potency of the Cu and Ag components of the CuO@AgO/ZnO NPs was enhanced tremendously to achieve such outcomes in vitro and in vivo . Considering the above advantages and facile preparation methods, the CuO@AgO/ZnO NPs synthesized in this work may prove as an important antibacterial agent in bacterial-related infection therapeutics and for biomedical-related purposes. Graphical abstract: Image 1 Highlights: CuO and AgO co-doped ZnO nanocomposites were prepared via high-temperature calcination. CuO@AgO/ZnO nanocomposites have good photothermal properties and stability under NIR irradiation. CuO@AgO/ZnO nanocomposites could significantly kill bacteria and eradicate biofilm in vitro. CuO@AgO/ZnO nanocomposites removed bacteria via photothermal therapy to promote wound healing in vivo.
