8-Arm PEG-Thiol (8-arm PEG-SH) is a multiarmed PEG derivative with thiol at each terminal of the eight arms. One hexaglycerol core connects all 8 arms through ether bonds. The reactive free thiol, SH, sulfhydryl, or mercapto selectively react with maleimide forming thioether bond. Thiol also PEGylates transition metal surface including gold, silver nanoparticles. PEG-SH can be easily air oxidized to form S-S disulfide bonds, which can be reversed with reducing agents. 8-Arm PEG-Thiol is a useful reagent for reversible PEGylation and forming PEG hydrogel.
