MPEG-SH Chemical Properties,Usage,Production

Description

m-PEG12-thiol is a PEG linker containing a thiol group. The thiol group reacts with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc. The hydrophilic PEG spacer increases solubility in aqueous media.

Uses

m-PEG-thiol (MW 1000) modifies DNA thiolation for the synthesis of gold nanorods (AuNRs). Thiolated DNA can be loaded onto AuNR by the mPEG-SH/Tween 20 assisted method (Tween 20 and mPEG-SH repeatedly displace CTAB on the AuNR surface). DNA AuNRs have been widely used in nanostructure assembly, gene therapy, biosensing, and drug delivery.
