Core-shell chitosan microsphere with antimicrobial and vascularized functions for promoting skin wound healing

It is imperative to develop a wound dressing that can effectively treat bacterial infection in the wound location and speed up wound healing. In this study, chitosan (CS) microspheres with a core–shell structure were prepared using high-voltage electrostatic drop technology. The antimicrobial polypeptide (PonG1) and bFGF, were encapsulated in the core of the CS microsphere. The preparation of CS microspheres was studied by changing the...
