23 Jul 3D printed Ti-PDA-BMP-2 bone defect repair tissue engineering scaffold and preparation method thereof
Abstract
The invention discloses a 3D printed Ti-PDA-BMP-2 bone defect repair tissue engineering scaffold and a preparation method thereof. The 3D printed Ti-PDA-BMP-2 bone defect repair tissue engineering scaffold is prepared from Ti6Al4V powder through a 3D printing technology and has a controllable shape, a pore microstructure and controllable physicochemical properties. A biological factor BMP-2 with bone repair ability is bonded to the engineering scaffold through polydopamine on the fiber surfaces and is used for repair and treatment on bone defects. The engineering scaffold has the advantages ofsimple and reliable structure, controllable shape and microstructure, simple and efficient surface modification, reliable mechanical property, high biological activity and safety, convenient implantation, small trauma and low cost.
