Abstract Cu-modified nanoparticles have been designed to mimic peroxidase, and their potent antibacterial and anti-biofilm abilities have been widely investigated. In this study, novel core–shell polydopamine (PDA)/Cu4(OH)6SO4 crystal (PDA/Cu) nanometer rods were prepared. The PDA/Cu nanometer rods show similar kinetic behaviors to chloride-activated peroxidases, exhibit excellent photothermal properties, and are sensitive to the concentrations of pH values and the substrate (i.e., H2O2). PDA/Cu nanometer rods could adhere to the bacteria and catalyze hydrogen peroxide (H2O2) to generate more reactive hydroxy radicals (OH) against Staphylococcus aureus and Escherichia coli, Furthermore, PDA/Cu nanometer rods show enhanced catalytic and photothermal synergistic antibacterial activity. This work provides a simple, inexpensive, and effective strategy for antibacterial applications.
