20-(16-Mercaptohexadecanyloxy)-3,6,9,12,15,18-hexaoxaeicosane-1-amine, hydrochloride. ApplicationSAM preparation, amine group coating,and hydrophilic surface.
Polyethyleneglycols (PEGs) are widely used for material modifications to improve hydrophilicity of the surface. PEG-coated materials are usually more stable under physiological conditions. Since Amino-EG6-undecanethiol has 6 ethylene glycol units, 11 carbon atoms, and an SH group at the end, it can be used to prepare a highly oriented and hydrophilic SAM on a gold surface. This is suitable for biomaterial labeling on the surface due to the improved hydrophilicity.
