Thiol PEG linkers have reactive thiol moiety on one side of the linear peg chain. The thiol functional group readily react with biomolecules with maleimide, halogen acetate, thiol, cysteine, and OPSS. It has also been widely used surface modification of gold, and silver, etc. Surface-grafted poly(ethylene glycol) (PEG) molecules are known to prevent protein adsorption to the surface.
