Abstract

Nanomaterials offer several significant advantages owing to their small size. High surface area/volume ratios allow for stronger signals, better catalysis and more rapid diagnostic of analytes, as well as enhanced optical properties. These nanoscale properties represent considerable benefits over macroscale materials.

Combinations of the dimensional, compositional and geometric properties of nanomaterials can reveal unique functionality and enable several applications. With this aim, the synthesis of particular functional nanomaterial with well-defined morphologies that are able to interact with organic molecules is a significant challenging. Functionalization of organic material onto different nanomaterials can generate films that are only one single molecule in thickness. These nanoscale films have been utilized extensively in the engineering of surfaces with well-defined properties.

In the biomedical field, single wall carbon nanotubes (SWCNT) also metallic nanowires have attracted considerable attention due to their properties for the application in optoelectronic and wearable devices. In addition to being less expensive in fabrication cost than other conductive materials, carbon and metallic nanowires also can be bent, stretched, compressed and twisted while remain conductive and reliable. Therefore, films made by nanowires has been reported as the best candidate as a material for future in manufacturing touch screens, solar cells, and other wearable devices. In this paper, we describe the alignment of SWCNTS+DNA on solid surface for the future development and applications of nanowires with its promising properties to achieve flexible optoelectronic and wearable devices.
