Long-term inflammation and persistent bacterial infection are primary contributors to unhealed chronic wounds. The use of conventional antibiotics often leads bacteria drug resistance, diminishing wound healing effectiveness. Nanozymes have become a promising alternative antimicrobial materials due their low cost, easy synthesis, good stability. Herein, we develop novel sprayable hydrogel based on carboxymethyl chitosan (CMCS) oxidized hyaluronic acid (OHA), incorporating Au nanoparticle-carbon nitride (AuNPs-C3N4) nanozyme, glucose, Mn2+ for bacteria-infected healing. forms rapidly in situ upon spraying gradually degrades the area, releasing AuNPs-C3N4 which exhibits robust glucose oxidase-like (GOx-like) activity, initiating comprehensive catalytic cascade through Mn2+-mediated Fenton-like reaction that generates hydroxyl radicals (•OH) eliminate Staphylococcus aureus (S. aureus) Methicillin-resistant S. (MRSA). Computational results indicate interactions between AuNPs g-C3N4 maximize synergistic effects heterojunction, improving O2 adsorption facilitating electron-O2 optimize activity. Further experiments demonstrate can cover wounds situ, while CMCS promotes collagen production fibroblast proliferation, offering viable strategy
