m-PEG3-thiol linker contains a thiol group. The thiol group reacts with maleimide, OPSS, vinylsulfone to form a C-S covalent bond. It can also form S-Metal bond on the surfaces of transition metals, such as gold, silver, etc. The mPEG spacer increases the aqueous solubility of the resulting compound and improves the hydrophilicity of the metal surfaces.
