Silane-PEG-COOH is a linear heterobifunctional PEG reagent with silane and carboxylic acid.
Ethoxy 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.
Typically, the functionalization of silica, known as silanization, begins with APTES and involves multiple steps to produce the desired functionality. However, with methoxy, azide, alkyne, and biotin functionalities, NSP’s silane PEGs greatly reduces the steps required to create the desired functionality.
