In vivo diabetic wound treatment studies. (A) Schematic of diabetic wound treatment. (B) Representative photographs of the wound treated with different treatments for 14 days. (C) Simulated images of wound healing in different treatment groups. (D) Wound size change during 14 days. Wound size at each time point was normalized to day 0. (E) Body weight of diabetic mice in different groups during treatments. (F) Blood glucose of diabetic mice in different groups during treatments. (G, H) Representative real-time thermographic images with NIR irradiation (1.0 W cm^− 2, 5 min) and the corresponding photothermal heating curves. Data are presented as the mean ± SD (n = 3). * p < 0.05, ** p < 0.01, and *** p < 0.001
