Propargyl-PEG3-triethoxysilane linker contains a triethoxysilane moiety and a propargyl group. Triethoxysilane is commonly used for surface modifications. The propargyl group can be reacted with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The hydrophilic PEG linker can increase the solubility of a compound in aqueous media and improve the hydrophilicity of the surfaces.
