Traditional wound care methods include wound infection control, adequate nutritional supplements, education of changing position every 2–3 h to avoid tissue hypoxia, vacuum assistant closure, debridement, skin graft, and tissue flap. Electric current stimulation, ultrasound, laser, and hydrotherapy have emerged as adjuvant therapies. However, most, if not all, of these therapies are expensive, and the treatment results are variable. The development of the active methods to improve wound healing is mandatory. CO2 administration has been known to improve microcirculation and local oxygen supply that are beneficial to wound healing. Here, the metal ion-ligand coordination nanoarchitecture was designed to reveal NIR light-induced CO2 generation for wound healing. The administration simply topically dropped the colloidal solution on the incisional wound, followed by exposure of near-infrared (NIR) lamp to yield CO2, resulting in the observation of the accelerated wound healing.
