Synthesis of Ag-AgCl@Au NMs and schematic diagram of PDT/PTT synergistic therapy under NIR-II irradiation. (A) Schematic diagram of the synthesis of Ag-AgCl@Au NMs. Schematic diagram and electron energy level diagram of O₂ reacting with electrons in AgCl nuclear conduction band to generate superoxide anion radical (O₂ ^-). (B) Schematic diagram of PDT/PTT synergistic therapy under in vivo NIR-II light irradiation of Ag-AgCl@Au NMs. Under NIR-II light irradiation, the plasmonic effect of Au nanostructures generates O₂ through photocatalysis and enhances the yield of O₂ ⁻.
