Sh-peg-sh is one of the same bifunctional PEG derivatives, which has free mercaptan groups at each end of PEG. Mercaptan can react with many mercaptan reactive groups, such as maleimide, iodoacetamide, pyridyl disulfide, etc. Mercaptan groups also have high binding affinity to noble metal surfaces, such as gold and silver.

Thiolated peg can be used for the surface modification of gold or silver particles, and widely used for the modification of gold nanoparticles or gold films. Sulfhydryl groups can produce stable thioether bonds with maleimide, which is widely used in the field of medicine and biology.
