Abstract

We demonstrated DNA-template assembly of gold-nanoparticles AuNP via step-by-step binding reaction. The control of hydrophilicity for mica surface makes it possible to preserve the structure of AuNP-binded DNA network with resistance to Au-thiolate reaction in ethanol solvent. This method realizes the formation of a continuous AuNP array with uniform height and small width. [DOI: 10.1380/ejssnt.2004.222]
