A method of making a semi-synthetic scaffold is described. The method includes mixing a gelatin solution, a high molecular weight chitosan solution, and a hyaluronate solution, to form a polymeric liquid solution; pouring the polymeric liquid solution into a mold; gradually cooling the mixture to gellify and form a polymer matrix; and freezing and lyophilizing the polymer matrix to remove water and form a scaffold. Semi-synthetic scaffolds, and methods of using them for wound healing, are also described.
