Determinations of the loading efficiency of DOX loaded into CMS/PEG and catalase- and glutathione reductase-like activities of CMS/PEG. A DOX-loading efficiency as a function of different DOX:CMS/PEG weight ratios. B The maximum UV-Vis absorbance curves of H2O2 in CMS/PEG solutions of three different pH values over time. C The maximum UV-Vis absorbance curves of MB that reacts with hydroxyl free radical (·OH) in the solutions of three different pH values with time. D The maximum UV-Vis absorbance curves of GSH as a function of CMS/PEG concentration with three different pH values. E The photothermal activity of CMS of different concentrations (200 μL) under infrared laser irradiation (808 nm, 1 W·cm− 2) for 5 min. F DPBF consumption by ·O2− produced from CMS/PEG (50 μg·mL− 1) under laser irradiation (808 nm laser, 1 W·cm− 2) as a function of irradiation time. DOX, doxorubicin; MB, methylene blue; GSH, glutathione; CMS, Cu2MoS4; PEG, polyethylene glycol; DPBF, 1,3-diphenylisobenzofuran
