23 Jul Tissue engineering scaffold material of chemical bonding active material and preparation method thereof
Abstract
The invention provides a tissue engineering scaffold material of a chemical bonding active material and a preparation method of the tissue engineering scaffold material. The tissue engineering scaffold material of the chemical bonding active material is prepared by a biodegradable macromolecular substance and an active material, wherein the macromolecular substance is counted by 100 parts by weight, and the active material is 0-15 part(s) by weight but is not zero; the 100 parts by weight of the macromolecular substance consists of 50-100 parts by weight of the synthesized macromolecular substance and 0-50 part(s) by weight of natural macromolecular substance; and a macromolecular nano-fiber film or a composite macromolecular nano-fiber film is formed by the macromolecular substance by means of electrostatic spinning, and the active material is evenly bonded on the surface of the fiber film. The tissue engineering scaffold material of the chemical bonding active material provided by the invention is good in biocompatibility, enough in mechanical strength, biodegradable, and suitable for stem cell proliferation and directed differentiation, and has the functions of cell migration adhesion promotion and stem cell capture to induce the regeneration of tissues such as bone, cartilage, nerve, skin, etc.
