Thiol-PEG3-phosphonic acid linker contains a thiol group and phosphonic acid end group. The thiol group can react with maleimides, disulfides, haloacteamides and other thiol groups. It also shows strong affinity to transition metal surfaces. Both thiol and phosphonic acid are used for surface modification. The hydrophilic PEG linker can increase the solubility of a compound in aqueous media and improve the hydrophilicity of the surfaces.
