摘要：
The various embodiments herein provide an electro spun wound dressing comprising three nano fibrous layers and a method of synthesizing the same. The outer polymeric layer acts as a support layer for the other two layers and is hydrophilic in nature. The middle layer comprises a genipin cross linked reservoir layer loaded with a herbal extract of Melilotus officinalis and is hydrophobic or hydrophilic in nature. The second layer is cross-linked to control a release of the Melilotus officinalis extract in an aqueous environment. The third layer is a wound contacting inner layer comprising a non-cross-linked chitosan based nanofibrous layer that is hydrophilic in nature. Various additives are provided to enhance the mechanical or the chemical properties of the wound dressing and to control a release profile of the herbal extract.
