Skin is the outermost and largest o

Skin is the outermost and largest organ in the body which protects the underlying tissues from external damage. In the case of deep injuries and burms, the process of healing is sometimes insufficient, thus leading to a chronic wound if not treated properly. Using appropriate wound dressings can often provide a suitable environment for normal tissue reconstruction and promote the healing process. An ideal wound dressing should be biocompatible and mechanically flexible, protect damaged regions from fluid loss and bacterial invasion, allow for gaseous exchange, and absorb excess exudates.So far, several kinds of wound dressings have been constructed such as rubber, foam, electrospun nanofiber,membrane, and hydrogel etc. Among these dressings, electrospun polymeric nanofibers, owing to their intrinsic porous structure and high specific surface area, have displayed numerous desired features to be used as wound dressing materials. Among the wide range of natural and synthetic po
