a Synthesis scheme of the Ag+ doped polymer-functionalized BP nanosheets and the self-assembly process into aqueous stable vesicles. b Therapeutic mechanism of the composite vesicle for combinational photodynamic/immunotherapy of resected solid tumors as well as the prevention of local bacterial infection. c Photographs of the E. coli-infected wounds after different treatment. d Changes in wound boundaries after different treatment. Blue area indicates original wounds, while green area indicates wounds after specific treatment for different days. e Changes in wound areas after different treatment. f Changes in the number of bacteria in the wound area after different treatment with PBS, BP Ve AND BP Ve-Ag+.
