catechol anchors coupled to poly(ethylene glycol) (PEG) for surface modification of TiO(2) are reported. Dopamine is modified by dimethylamine-methylene (7) or trimethylammonium-methylene (8) groups, and the preparation of mPEG-Glu didopamine polymer 11 is presented. All these PEG polymers allow stable adlayers on TiO(2) to be generated through mild dip-and-rinse procedures, as evaluated both by variable
合成和评估新的基于多巴胺的邻苯二酚锚定与聚乙二醇(PEG)的TiO(2)的表面改性的评价。用二甲胺-亚甲基(7)或三甲基铵-亚甲基(8)修饰多巴胺,并提出了mPEG-Glu多巴胺聚合物11的制备方法。所有这些PEG聚合物都允许通过温和的浸入和漂洗程序在TiO(2)上生成稳定的添加剂,这通过可变角度光谱椭圆偏光法和X射线光电子能谱进行了评估。当暴露于完全的人血清中时,所得表面显着降低了蛋白质吸附。
