Zein-polycaprolactone core–shell nanofibers for wound healing

•Coaxial electrospinning can be used to produce zein-PCL nanofibers.•Sustained antimicrobial drug release can be achieved from zein-PCL nanofibers.•Zein-PCL nanofibers are water stable, ductile and show good mechanical strength.•Zein-PCL nanofibers with T show good antimicrobial activity and cytocompatibility.•Zein-PCL nanofiber scaffolds allow attachment of fibroblasts.
