SHs simultaneously perform hyperthermia and deliver DOX for treating cancer. a) Macroscopic views and temperature distribution of the hydrogel samples before and after NIR irradiation. Scale bar: 1 cm. b) Volume contraction ratio of hydrogels with different PDA NPs contents. c) Cumulative DOX release curves of the hydrogels with/without NIR irradiation. d) Temperatures of mice tumors under different treatments within 10 min. f) Relative tumor volume and h) body weights of mice under different treatments within 15 days. e) Photographs and g) weights of mice tumors under different treatments at the 15th day.
