乙氧基或甲氧基硅烷功能化聚乙二醇、硅烷PEG (PEG- si)是一种表面反应性的PEG衍生物,可通过羟基与乙氧基/甲氧基硅烷之间的反应来修饰玻璃、二氧化硅等表面。聚乙二醇化可以极大地抑制带电分子与修饰表面的非特异性结合。它们在医疗器械、生物制剂或生物相容性材料的开发中有着广泛的应用。
Ethoxy or methoxyl silane functionalized polyethylene glycol, silane PEG (PEG-Si) is a surface reactive PEG derivative that can be used to modify glass, silica and other surfaces via the reaction between hydroxyl group and ethoxyl/methoxyl silane. Pegylation can greatly suppress the non-specific binding of charged molecules to the modified surfaces. And they have wide applications for medica device, biomems or biocompatible material development.
