Chronic diabetic wounds are difficult to treat due to imbalanced inflammatory responses, high blood glucose levels, and bacterial infections. Novel therapeutic approaches based on nucleic acid analogues have been proposed, with unique advantages in improving angiogenesis, increasing collagen synthesis, and exerting anti-inflammatory effects. However, the inherent electronegativity of nucleic acids makes them less susceptible to cellular uptake. In this paper, a kind of near infrared (NIR)-responsive nanocomposite hydrogel loaded with nucleic acid vectors was proposed for promoting wound healing. The redox system composed of molybdenum disulphide nanosheets (MoS
