Carboxyl-Functionalized PEG for Surface Modification

Silane-PEG-COOH (Silane-PEG-Acid) is a PEG chain terminated with a silane group and a carboxylic acid (COOH) functional group. The silane group enables covalent attachment to various surfaces, including glass, silicon, and metal oxide surfaces, through silanization reactions, forming stable bonds with the substrate. The carboxylic acid group provides a site for conjugation with molecules containing complementary functional groups, such as primary amines, through amide bond formation.

Silane-PEG-COOH is commonly employed in the development of functionalized surfaces, biosensors, drug delivery systems, and biomaterials due to its versatility, biocompatibility, and ability to introduce specific functionalities to surfaces or molecules.
