23 Jul Skin scaffold material for tissue engineering and preparation method thereof
Abstract
The invention provides a skin scaffold material for tissue engineering. The skin scaffold material for tissue engineering consists of a hyaluronic acid scaffold and a nanofiber membrane; the hyaluronic acid scaffold is prepared by loading superoxide dismutase liposome on a hyaluronic acid porous scaffold; and the nanofiber membrane is prepared from a chitosan/keratin mixed solution. The inventionalso provides a preparation method of the skin scaffold material for tissue engineering, and the double-layer skin scaffold material prepared by adopting a method combining an electrostatic spinning technology and a freeze drying technology solves the problems of poor biocompatibility and improper pore diameter of a skin scaffold material and solves the problem that a wound skin is influenced by harmful metabolites. In addition, the preparation method is simple, and the skin scaffold material is green and environmentally friendly.
