多巴胺改性海藻酸多孔支架的制备与性能
Preparation and Properties of Polydopamine and Alginate Porous Complex Scaffolds
摘要
Abstract
Alginate( Alg) is widely used in the field of tissue engineering because of its safe, non-toxic and biodegradable properties. Inspired by mussel adhesive protein, dopamine ( DA ) has excellent adhesion property and can self-oxidize to polydopamine( PDA) in weak basic buffer solution.Alg/PDA porous scaffolds were prepared by freeze-dry of Alg and PDA mixture.The results show that Alg/PDA porous scaffolds have relatively homogeneous internal structure.By changing the mass concentration of Alg, the pore size of the Alg/PDA complex scaffolds can be limited to 60~120μm, and the porosity of the scaffolds can be controlled in the range of 80%~88% which is appropriate for the growth of bond cells.The biocompatibility results indicate that the scaffolds show low cytotoxicity.关键词
