乙氧基或甲氧基硅烷功能化的聚乙二醇(即硅烷化PEG,简称PEG-Si)是一种具有表面反应活性的PEG衍生物;利用其硅烷基团(乙氧基或甲氧基硅烷)与表面羟基之间的反应,可对玻璃、二氧化硅及其他材料表面进行改性。经此类PEG改性后,可显著抑制带电分子在表面上的非特异性结合,因此在医疗器械、生物微机电系统(BioMEMS)及生物相容性材料的开发领域具有广泛应用。
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.
