23 Jul Method for producing composite PGA/DMBG bone stent from polydopamine modified mesoporous bioglass
Abstract
The invention discloses a method for producing a composite PGA/DMBG bone stent from polydopamine modified mesoporous bioglass. The method comprises the following steps: modifying polydopamine by usingan in-situ polymerization method on the surface of an MBG powder to obtain a DMBG powder; mixing the DMBG powder and a PGA powder by a liquid phase, performing solid-liquid separation to obtain a solid, drying and grinding the solid to obtain a composite PGA/DMBG powder; and performing selective laser sintering on the obtained composite PGA/DMBG powder to obtain a composite PGA/DMBG bone stent. The composite stent has the good Biological activity, cell response and enhanced mechanical properties and has a broad application prospect in the tissue engineering field.
