A single-component photo-crosslinked chitosan hydrogel with inherent antimicrobial and antioxidant capabilities for wound healing

. Simultaneously, the LA component confers remarkable antioxidant capacity, effectively scavenging reactive oxygen species (ROS) at the wound site. In a full-thickness skin defect model, the LQCS hydrogel significantly accelerated wound closure by mitigating inflammation and promoting angiogenesis. This study presents a simple yet effective strategy for creating an all-in-one hydrogel dressing, which integrates green fabrication, multi-bioactivity, and pro-healing functions, holding great potential for advanced wound care.
