DNA-Templated Nanowire Fabrication Technique Developed

DNA-templated nanowire fabrication.

DNA-based nanotechnology is a vibrant and expanding field. The specific molecular recognition properties and large aspect ratio of DNA make the molecule a promising template for bottom-up fabrication of nanowires and nanodevices. Fabricating well-defined DNA-templated nanowires requires aligned surface deposition and specific metallization of DNA molecules. DNA localization on surfaces has been...

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

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 int...

Fabrication of Defined Polydopamine Nanostructures by DNA Origami‐Templated Polymerization

A versatile, bottom-up approach allows the controlled fabrication of polydopamine (PD) nanostructures on DNA origami. PD is a biosynthetic polymer that has been investigated as an adhesive and promising surface coating material. However, the control of dopamine polymerization is challenged by the multistage-mediated reaction mechanism and diverse chemical structures in PD. DNA origami decorated...

TiO2 nanowire-templated hierarchical nanowire network as water-repelling coating

Extraordinary water-repelling properties of superhydrophobic surfaces make them novel candidates for a great variety of potential applications. A general approach to achieve superhydrophobicity requires low-energy coating on the surface and roughness on nano- and micrometre scale. However, typical construction of superhydrophobic surfaces with micro-nano structure through top-down fabrication i...
