Abstract
AbstractEasy cancer recurrence and wound infections have been clinical challenges after surgical treatment of melanoma. Herein, a silk‐inspired in situ gelation system containing methacrylated silk fibroin (SF) and chlorine e6 for improved cancer therapy with enhanced wound healing is developed. Favored by the macrophage recruitment capacity of the SF hydrogel, promising antitumor immune responses can be turned “on” via near infrared irradiation in a controllable manner to achieve combination therapy with photodynamic therapy to significantly suppress melanoma recurrence. Moreover, the effective photodynamic antibacterial activity of this bioactive system with the capacity of light‐controllable modulating macrophage phenotype promotes remarkable tissue ingrowth with hair follicle regeneration for Staphylococcus aureus infected wound healing. Thus, this multifunctional silk‐based hydrogel system, as a desirable wound dressing, provides a new platform for promising melanoma therapy and skin regeneration.
