Abstract
A novel silk fibroin (SF) based bi-layered wound dressing was successfully developed by spraying chitosan (CS) solution on the ring spun silk fibroin fabric. SEM micrographs showed that chitosan solution formed a thin film on the degummed silk fibroin fabric, which had a connective porous structure. The antibacterial property, indirect cytotoxicity and the wound healing properties of the materials were investigated. Comparing with the commercial wound dressing, the bi-layered SF/CS wound dressing could accelerate the wound healing, and may be a potential choice for skin regeneration.
