Abstract
The most important aspect of fabrication of Carbon Nanotubes (CNTs) based devices/sensors is the selective and controlled positioning of CNTs, which is a challenging issue for the researchers now a days. Here, we have presented a simple and efficient methodology for positioning of CNTs using 16-MHA self-assembled monolayers (SAMs), written over the gold substrate using Dip-pen Nanowriting (DPN). The analysis of the obtained AFM images clearly shows significant height increment of nanopatterns, which corresponds to the attachment of carbonaceous material over the written nanopatterns.
