M-PEG-thiol (MW 550)

M-PEG-thiol (MW 550) 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.
