Selective Attachment of Functionalized Carbon Nanotubes on Templates Fabricated by AFM and Nanosphere Lithography

Abstract

We have investigated a selective attachment of functionalized single-walled carbon nanotubes (SWNTs) on templates. Our efforts have been concentrated on both functionalization of carbon nanotubes and their binding onto templates such as Si-wafer and gold. The alignment of SWNTs was performed by modifying the SWNTs with carboxylic acid, carboxylic chloride and alkyl thiol groups. Functionalized SWNTs were selectively immobilized through the formation of amide bonds using a coupling reagent onto prepatterned nanostructures by a self-assembly method. The characterization of chemically attached carbon nanotubes has been investigated using various surface characterization tools like AFM, TEM, SEM, and FT-IR.
