Abstract
Bacterial infection and free radical oxidative stress at the wound site could easily cause cascade inflammation and hinder the healing process of the wound. In this study, chitosan-cysteine-gallic acid (CCG) hydrogel with antibacterial and antioxidant properties was synthesized by chitosan (CS), cysteine (Cys), and gallic acid (GA) for a preliminary evaluation of its therapeutic efficacy in a mouse model of full-layer skin defect. In vitro analysis showed that the CCG hydrogel had good antibacterial activity and blood compatibility. In vivo, the CCG hydrogel wound dressings accelerated wound healing, stimulate angiogenesis, increase collagen deposition and anti-inflammatory factor expression. The CCG hydrogel wound dressing is designed to promote the regeneration of damaged skin tissue and is expected to become a potential candidate for clinical treatment.
