Fabrication of Anchor and DNA for Nanowire Bridging

Abstract

In this research, we propose a new method to apply DNA for the formation of nano-wires. Nano-oxidation experiments were conducted on a silicon substrate by atomic force microscopy (AFM) to produce nano-dots as anchors for DNA fixing. After the substrate was treated with a solution containing 2 μm DNAs modified with thiol at the both ends, which can chemically connect with the dots, the anchors were bridged by the DNAs. The DNA nanowires were observed by AFM.
