Abstract
In today's emergency medical field, rapid hemostasis and wound healing technologies are of paramount importance. However, traditional methods, although effective, have limitations such as slow hemostasis, susceptibility to infection, and unsuitability for irregular wounds. To address these issues, this study combined methacrylated hyaluronic acid (HAMA) with zinc chondroitin sulfate (CSZn) to successfully develop a novel sprayable photocurable hydrogel, CSZn@HAMA. Material characterization confirmed that CSZn was effectively loaded into HAMA, while retaining HAMA's photocurable and sprayable properties. This allows the CSZn@HAMA hydrogel to rapidly solidify and form a tight protective film over the wound after spraying. Further cell experiments demonstrated that this hydrogel has significant anti-inflammatory effects and can effectively promote collagen production and angiogenesis. Therefore, CSZn@HAMA has emerged as a promising biomaterial for wound management in emergency medical care.
