4T1 Tumor cell growth inhibition mediated by NLG919/IR780‐micelle‐based PTT and immunotherapy. A) Administration route of NLG919/IR780‐micelle‐mediated PTT and immunotherapy. B) Photothermal conversion of NLG919/IR780 micelles in vivo. Right) Infrared thermal images of mice treated with 1.0 and 2.0 mg kg⁻¹ b.w. Left) Surface temperature of tumor site versus irradiation time (IR780: 2.0 mg kg⁻¹ b.w.). C) Tumor volume of primary tumor and secondary tumor versus time, respectively (n = 6). D) Images of the tumor‐bearing mice 26 d after the primary tumor cells were implanted. (Right: primary tumor, green circle, 4T1 tumor. Left: secondary tumor, red circle, 4T1‐LUC tumor.)
