Abstract
In this report we combine the non-covalent functionalization of carbon nanotubes (CNTs) by DNA with the self-assembly technique to attach vertically aligned DNA-wrapped CNTs on gold substrates. The self-assembled adsorption of DNA-CNT complexes was characterized mainly by electrochemical techniques such as cyclic and linear sweep voltammetry. In addition, electrochemical desorption was used as a methodology to vary the surface coverage of the monolayer and to perform the complete removal of the species from the surface. The results suggest that the methodology used represents a straightforward route for the attachment of CNTs on solid substrates, and further studies will allow the development of novel nanodevices and sensors based on DNA-CNT self-assembled monolayers (SAMs).
