A high-performance dressing with both antibacterial and anti-inflammatory properties was developed by incorporating an anti-inflammatory and antibacterial drug, rhein, into a silk fibroin matrix. The resulting hydrogel dressing exhibited a fibrous network nanostructure, high water content, and water adsorption ability, making it suitable for treating bacterial infected wounds and accelerating wound healing.
Advanced dressings that can simultaneously prevent bacterial colonization/infection and reduce inflammation are highly desired. A simple strategy was developed to incorporate an anti-inflammatory and antibacterial drug rhein into the structure of silk fibroin (SF) matrix to fabricate a hydrogel dressing. The SF/Rhein hydrogels showed fibrous network nanostructure, high water content (~90%), high water adsorption ability (>2 folds of its own weight), acceptable mechanical strength, biocompatibility and antibacterial properties, suitable as dressings for the treatment of bacterial infected wounds. The SF/Rhein hydrogels enhanced the healing rate of burn wounds by reducing inflammation, expediting angiogenesis, and promoting skin appendages formation, being a promising candidate as wound dressings.
