Abstract

The repair of methicillin-resistant staphylococcus aureus (MRSA) infected wounds remains a serious challenge. Development of multifunctional bioactive hydrogels has shown promising potential in treating MRSA wound. Ferulic acid has special bioactivities including antioxidant antiinflammation antibacterial capacities but limited in lack of engineering strategy for efficient treatment of MRSA infected wound. Herein, we developed a multifunctional bioactive poly(ferulic acid) copolymer (FPFA) for treating MRSA infected wound. FPFA could be self-assembled into hydrogel under body temperature and demonstrated the injectable, sprayable, self-healing, anti-inflammatory, antioxidant, and angiogenic activity. FPFA hydrogel also showed the good cytocompatibility, efficiently enhanced the endothelial cell migration, scavenged intracellular reactive oxygen species (ROS), inhibited the expression of inflammatory factors and enhanced the in vitro angiogenesis. The MRSA-infected wound model showed that FPFA could significantly inhibit the MRSA infection and excess inflammation, reinforce the angiogenesis, accelerate wound healing and skin tissue regeneration.

Keywords: bioactive materials; multifunctional bioactivity; tissue engineering; wound repair.
