In vivo antitumor performance and safety evaluation in the 4T1 tumor-bearing mice. Temperature increase profiles (A) and infrared thermal images (B) of the 4T1 tumor-bearing mice irradiated with laser (IR820-SS-CPT NPs: 660 nm, 1.0 W/cm2; IR820: 808 nm, 1.0 W/cm2). C Tumor volume changes of the mice treated with PBS, IR820, IR820 + NIR, CPT, IR820-SS-CPT NPs, and IR820-SS-CPT NPs + NIR. D Body weight curves of the 4T1 tumor-bearing mice during the treatment. Tumor weight (E) and the representative photographs of excised tumors (F) of each group. *P < 0.05, **P < 0.01, ***P < 0.001
