m-PEG-thiol (MW 550) is used to modify thiolated DNA for the synthesis of gold nanorods (AuNR). The mPEG-SH/Tween 20 assisted method (involving repeated replacement of CTAB on the AuNR surface with Tween 20 and mPEG-SH) enables the loading of thiolated DNA onto AuNR. DNA AuNR has been extensively utilized in nanostructure assembly, gene therapy, biosensing, and drug delivery.
