Nevertheless, redundant ROS during treatment inevitably bring detriments in revascularization. To address this dilemma, an innovative P\u2010N bio\u2010heterojunction (bio\u2010HJ) material consisting of p\u2010type copper sulfide (p\u2010CuS), n\u2010type bismuth sulfide (n\u2010Bi\n                    <jats:sub>2<\/jats:sub>\n                    S\n                    <jats:sub>3<\/jats:sub>\n                    ), and lactate oxidase (LOx) for effective treatment of recalcitrant infectious wounds by promoting angiogenesis is devised. LOx exhausts lactic acid accumulated in infection environment and converts it to hydrogen peroxide (H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    ), which subsequently yields bactericidal hydroxyl radicals (\u00b7OH) via Fenton\u2010like reactions. Ultimately, the P\u2010N bio\u2010HJs exert synergistic photothermal, photodynamic, and chemodynamic effects for rapid bacterial annihilation. Moreover, in vitro and RNA\u2010seq analyses reveal that the crafted bio\u2010HJs dramatically expedite the proliferation of L929 cells and promote angiogenesis by up\u2010regulating angiogenic gene expression in hypoxia\u2010inducible factor\u20101 (HIF\u20101) signaling pathway, which may ascribe to the evolution of H\n                    <jats:sub>2<\/jats:sub>\n                    S in response to the infection microenvironment. Critically, results of in vivo experiments have authenticated that the bio\u2010HJs significantly boost healing rates of full\u2010thickness wounds by slaughtering bacteria, elevating angiogenesis, and promoting cytothesis. As envisioned, this work furnishes a novel tactic for the effective treatment of bacteria\u2010invaded wound using H\n                    <jats:sub>2<\/jats:sub>\n                    S\u2010liberating
