Effects of thermosensitive black phosphorus hydrogel on wound healing in vivo. A Schematic illustration of hydrogel promoting wound healing. B Wound images of different groups after the wound area was treated on days 0, 3, 7, and 14 after surgical resection. Scale bar: 5 mm. C Schematic diagram of wound healing simulated by image software in Control group (c1), NIR group (c2), BP@Gel group (c3) and BP@Gel + NIR group (c4). D Graph of body weight change in rats during wound healing. E Wound area map. F Graph of wound healing rate. (*P < 0.05, **P < 0.01, ***P < 0.001)
