Methoxy PEG Thiol (mPEG-SH) is a linear monofunctional PEG, which has a free thiol group at one end that can selectively react with maleimide and transition metal surface including gold, silver, etc. mPEG SH is commonly used to modify gold or silver nanoparticles. Also, it can be easily oxidized by air through S-S disulfide bonds to form dimers, which can be reversed with reducing agents.
