Photothermal effect of the DOX/IR780 NPs. A) Changes in temperature for a saturated solution of free IR780 and a suspension of the DOX/IR780 NPs upon irradiation by the 808-nm NIR laser at a power density of 0.4 W cm−2. B) Comparison of the photothermal heating behaviors for the free IR780 and DOX/IR780 NPs after repeated cycles of laser irradiation. C) Fluorescence enhancement ratio of DCFH activated by free IR780 and the DOX/IR780 NPs upon laser irradiation at a power density of 0.4 W cm−2. D) Cumulative DOX release from the DOX/IR780 NPs upon laser irradiation at a power density of 0.4 W cm−2.
