In vivo photothermal therapy using CuS@MPG NPs. (A) Temperature evolution on tumors of MDA-MB-231 tumor-bearing mice with and without CuS@MPG NPs monitored with a thermometer during laser treatment. (B) The infrared thermal images from tumor region in laser-only group and agent+laser group, respectively (808 nm laser, 0.64 W/cm² for 10 min. The thermal images were taken in the last second of laser irradiation). (C) The tumor growth curves and (D) body weights of mice bearing MDA-MB-231 tumors after different treatments indicated (n = 5). (E) Representative photographs of mice in four groups 21 days after treatments. (F) Histological examination of vital organs (heart, liver, spleen, lung and kidney) of mice in agent+laser group at 21th day after treatments. Untreated healthy mouse was used as control. Scale bar = 50 µm.
