Electrospun Silk Material Systems for Wound Healing

The functional properties of six distinct electrospun silk material groups were evaluated to assess conformational and biocompatible characteristics related to wound dressings. In a hydrated state, all six silk matrices exhibited absorption, water vapor transmission, oxygen permeation and enzymatic biodegradation suitable for full-thickness wound sites. Employing constrained drying techniques, silk concentration was a determinate factor influencing material structural properties related to the storage and distribution of such wound dressing systems. Subsequently, three electrospun silk models demonstrated ideal biomaterial properties with potential utility for wound dressings.
