A facile in situ generation of dithiocarbamate ligands for stable gold nanoparticle–oligonucleotide conjugates

Abstract

Here we demonstrate a facile strategy of preparing gold nanoparticle (AuNP) and DNA conjugates by in situ generation of strong metal affinity capping ligands, dithiocarbamates (DTC) modified oligonucleotides; the conjugates produced are stable at elevated temperature, resistant to ligand displacement and preserve the functionality of the conjugated oligonucleotides.
