乙氧基或甲氧基硅烷官能化聚乙二醇,硅烷 PEG(PEG‑Si)是一类可用于表面修饰的活性 PEG 衍生物。它可通过羟基与乙氧基 / 甲氧基硅烷之间的反应,对玻璃、二氧化硅等基材表面进行改性。PEG 化修饰能够显著抑制带电分子在修饰表面的非特异性结合,广泛应用于医疗器械、生物微机电系统(BioMEMS)以及生物相容性材料的开发。
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.
