(a) Photothermal pictures of mice treated under 1060 nm laser irradiation (1 W cm⁻²) for different time points after being injected with TPR or TCPR NPs (200 µg mL⁻¹, 50 µL) and phosphate-buffered saline (PBS.) (b) Temperature changes in mice tumor sites corresponding to (a). (c) Variation in relative tumor volume after different treatments. (d–f) Dihydroethidium (DHE; red fluorescent signal indicates ROS concentration), hematoxylin and eosin (H&E), and Ki-67 staining of tumors with various treatments (***p < 0.001).
