Pathogenic bacteria are the main cause of bacterial infectious diseases, which have posed a grave threat to public health. Single-atom nanozymes have emerged as promising candidates for antibacterial applications, but their activities need to be further improved. Considering diatomic nanozymes exhibit superior metal loading capacities and enhanced catalytic performance, a new interlayer coupling diatomic nanozyme (IC-DAN) is constructed by modulating the coordination environment in an atomic-level engineering. It is well demonstrated that IC-DAN exhibited superior peroxidase-mimetic activity in the presence of H2O2 to yield abundant ∙OH and possessed high photothermal conversion ability, which synergistically achieves efficient antibacterial therapy. Therefore, IC-DAN shows great potential used as antibacterial agent in clinic and this study open a new route to developing high-performance artificial enzymes.
