Abstract

Deoxyribonucleic acid (DNA)-derivatized gold nanowires were discussed as the building blocks of surface assemblies. Oligonucleotides were adsorbed as monolayer coatings on the wires through gold-thiol linkages. Absorption and fluorescence spectroscopy were employed to quantify the amount of DNA bound. The nanowires were modified with single stranded (ss) DNA at specific sites with the remaining wire covered by passivating monolayers. The modification resulted in easy implementation of the site-specific DNA directed assembly.
