A facile and efficient method to modify gold nanorods with thiolated DNA at a low pH value

Chem Commun (Camb). 2013 Mar 28;49(25):2533-5. doi: 10.1039/c3cc39093d.

Abstract

We report a simple, rapid and efficient strategy for modification of gold nanorods (AuNRs) with thiolated DNA at low solution pH and high salt concentration. DNA functionalized AuNRs were then used to assemble with DNA modified gold nanoparticles to form discrete satellite nanostructures.
