DNA-Templated Fabrication of 1D Parallel and 2D Crossed Metallic Nanowire Arrays

Abstract

This paper reports a simple method for the fabrication of ordered nanostructures composed of metallic nanowires. Molecular combing was used to stretch and align linear λ-DNA molecules into parallel or crossed patterns. Subsequent metallization of DNA through electroless palladium deposition yielded 1D parallel or 2D crossed metallic nanowire arrays. This method has potential use in building interconnects between nanosized building blocks toward nanodevice construction.
