Treatment of diabetic foot ulcers (DFU) needs to reduce inflammation, relieve hypoxia, lower blood glucose, promote angiogenesis, and eliminate pathogenic bacteria, but the therapeutic efficacy is greatly limited by diversity synergy drug functions as well DFU microenvironment itself. Herein, an ultrasound-augmented multienzyme-like nanozyme hydrogel spray was developed using hyaluronic acid encapsulated l-arginine ultrasmall gold nanoparticles Cu1.6O coloaded phosphorus doped graphitic carbon nitride nanosheets (ACPCAH). This possesses five types enzyme-like activities, including superoxide dismutase (SOD)-, catalase (CAT)-, glucose oxidase (GOx)-, peroxidase (POD)-, nitric oxide synthase (NOS)-like activities. The kinetics reaction mechanism sonodynamic/sonothermal synergistic enhancement SOD-CAT-GOx-POD/NOS cascade ACPCAH are fully investigated. Both in vitro vivo tests demonstrate that this can be activated thus accelerating wound healing effectively. study highlights a competitive approach based on nanozymes for development all-in-one therapies.
