Abstract
Rapid hemostasis and wound healing are crucial in emergency trauma situations for saving patients' lives. Traditional hemostatic materials often have drawbacks such as slow hemostasis and susceptibility to post-hemostasis bacterial infections. Therefore, there is an urgent need for advanced wound dressing materials that can provide both rapid hemostasis and antimicrobial properties. In this study, we designed and fabricated a biocompatible hemostatic silk fibroin (SF) aerogel loaded with aggregation-induced emission (AIE)-featured berberine (BBr) and Ti3C2Tx MXene. The resulting SFMB aerogel demonstrates robust mechanical properties and a porous structure that enables quick hemostasis. This aerogel exhibits photodynamic and photothermal responses for antimicrobial activity, releases BBr upon light exposure to enhance bacterial-killing efficiency (99.33 % in vitro and 99.09 % in vivo), and effectively promotes the healing of infected wounds in vivo through combined photothermal/photodynamic antibacterial and anti-inflammatory mechanisms. Furthermore, the aerogel shows high hemocompatibility and cytocompatibility, supporting its potential biomedical applications. Overall, the synthesized SFMB aerogel holds promise for treating bacteria-infected wounds and for use in first aid applications in clinical settings.
