Poly(ethylene glycol) methyl ether thiol (mPEG-SH, mPEG-Thiol, Methoxy PEG Thiol) is a thiol-terminated biocompatible polymer widely used in the surface functionalization of gold nanoparticles. Thiol moieties bind with high affinityto gold surfaces by forming a self-assembled monolayer (SAM) through thecovalent thiolate–metal bond. mPEG-thiol-coated Au nanoparticles find applications in the fields of biosensors and drug delivery systems.
