a) Infrared thermographic images and b) photothermal heating curves of breast tumor‐bearing nude mice under different treatments. c) Time‐dependent tumor volume of nude mice under different treatments. For the 650 nm light treatment, the power density was 0.5 W cm⁻², and the irradiation time was 10 min. For the 808 nm light treatment, the power density was 1.0 W cm⁻², and the irradiation time was 10 min. d) Images of representative tumors after treatment with various formulations. e) Time‐dependent body weight of mice under different treatments. f) Histopathological examinations via hematoxylin and eosin (H&E) staining of major organs from mice treated with BM‐PEG NSs. Images were taken under 20× objective.
