Mussel-inspired hydrogels with wet adhesion and anti-inflammatory properties for oral and pressure ulcers

environments. The DCFH-DA experiments showed that the GD3M4 hydrogel has good antioxidant properties. In both the mouse oral ulcer model and pressure ulcer model, the GD3M4 hydrogel exhibited excellent ulcer-healing effects by modulating the expression of inflammatory factors and epidermal growth. In conclusion, the GD3M4 hydrogel provides a promising therapeutic strategy for promoting the healing of oral ulcers and pressure ulcers.
