Photothermal characterizations of PC10A/DOX/HAuNS hydrogels. a Temperature changes of PC10A/DOX/HAuNS nanogels (PC10A: 0.1% w/w, DOX: 0.8 mg mL−1) containing different concentrations of HAuNS (25, 20, 15, 10, 5, and 0 μg mL−1) under irradiation with an 808 nm laser for 9 min (2.0 W cm−2); b photothermal stability of the HAuNS under six irradiation on/off cycles (808 nm, 2.0 W cm−2); c temperature changes of the PC10A hydrogel, PC10A/HAuNS hydrogel, and PC10A/DOX/HAuNS hydrogel (PC10A: 3% w/w, DOX: 0.8 mg mL−1, HAuNS: 20 μg mL−1) under irradiation (2.0 W cm−2) with an 808 nm laser for 9 min; d temperature changes of the PC10A/DOX/HAuNS nanogel (PC10A: 0.1% w/w, DOX: 0.8 mg mL−1, HAuNS: 20 μg mL−1) under laser irradiation (808 nm, 2.0 W cm−2) for 9 min and cooling for 16 min. n = 3
