The application of BSA-Ce6@IrO2/MnO2 NPs as photothermal agents for the induction of local hyperthermia production and acidic H2O2-enhanced generation of O2 and 1O2. (A) A schematic illustration. (B) Heating curves of BSA-Ce6@IrO2/MnO2 dispersions at different Ir concentrations. (C) Heating curves at a fixed Ir concentration of 3.0 mM with different laser powers. (D) Photothermal images of BSA-Ce6@IrO2/MnO2 dispersions with different Ir concentrations irradiated for 5 min at varied power densities. (E) Schematic illustration of BSA-Ce6@IrO2/MnO2 generating O2 from H2O2. (F) The generation of oxygen determined by quenched RDPP fluorescence. (G) Consumption of DPBF triggered by BSA-Ce6@IrO2/MnO2, without or with 660 nm light irradiation and at different concentrations of H2O2 (0, 0.1 and 0.2 mM).
