Multifunctional composite wound dressings hold significant promise for diabetic healing. However, the detrimental role of advanced glycation end-products (AGEs)-reactive oxygen species (ROS) cycle in impeding repair remains underexplored. To disrupt this pathological cycle, zeolitic imidazolate framework-8 (ZIF-8) encapsulated cerium dioxide (CeO2) and adsorbed glucose oxidase (GOx) nanozyme particles ((ZIF-8@CeO2)@GOx, zcg) were loaded into a methacrylic anhydride-modified gelatin (GelMA) hydrogel to form sprayable dressing, zcg/GelMA (zcgG). Physicochemical characterization revealed that GOx catalyzes oxidation, triggering ZIF-8 acid-mediated decomposition release zinc ions CeO2 nanoparticles, thereby enabling cascade depletion, antioxidant, antiglycation functions. In vitro antimicrobial cytotoxicity experiments optimized zcg concentration GelMA. Under oxidative hyperglycemic culture conditions, we validated mechanism blocking AGEs-ROS restoring fibroblast mitochondrial membrane potential, subsequently suppressing cellular senescence. bacterial-infected rat skin model, zcgG group demonstrated substantially reduced inflammatory levels, 68% decrease AGEs, 1.9-fold increase collagen deposition compared blank controls. Within 2 weeks, achieved complete closure, while control retained 28% initial area. This work provides preliminary evidence feasibility using nanozymes break promote
