SURFACE TAILORING OF PTFE FOR ENDOTHELEAL CELLS SELECTIVITY BASED ON POLYDOPAMINE-ASSISTED SELF-ASSEMBLY MONOLAYER TECHNIQUE
基于聚多巴胺辅助自组装单分子层技术的PTFE表面修饰及其内皮细胞选择性黏附研究

An endothelial preferential PTFE was developed via polydopamine-assisted self-assembly monolayer (SAM) technique. XPS,ellipsometer,QCM-D and contact angle data confirmed the self-polymerization process of DOPA and subsequently self-assembly monolayer formation of CGREDVDY. In cell adhesion experiments, both endothelial cells ( ECs) and smooth muscle cells ( SMCs) exhibited improved attachment on DOPA modified PTFE surfaces,but the surfaces did not have noticeable preference between the two cell types.
