Injectable Therapeutic Hydrogel with H2O2 Self‐supplying and GSH Consumption for Synergistic Chemodynamic/Low‐temperature Photothermal Inhibition of Postoperative Tumor Recurrence and Wound Infection

Postoperative tumor recurrence and wound infection remain significant clinical challenges in surgery, often requiring adjuvant therapies. The combination treatment of photothermal therapy (PTT) and chemodynamic therapy (CDT) has proven to be effective in cancer treatment and wound infection. However, the hyperthermia during PTT increases the risk of normal tissue damage, severely impeding its application. Moreover, the efficacy of CDT is limited by insufficient hydrogen peroxide (H
