Carbon nanotubes architectures in electroanalysis

Electroanalysis is one of the promising analysis methods for various aspects. Carbon nanotubes (CNTs), a novel carbon form, has been also exploited as an electrode material in electroanalysis as a result of its extraordinary electronic, chemical and mechanical properties. In addition, CNTs is also stable and robustness and is compatible with various chemical and biological species, hence the nanotubes’ abilities recognized to various analyzes associated to those species. However, not only the electrode materials can influence the electrode electrochemical properties, but also the electrode orientation or architecture does. This paper, therefore, reviews various carbon nanotubes (CNTs) oriented architectures practically employed in electroanalysis for different purposes. Those include 1) CNTs casting films and CNTs polymer composites, (2) CNTs paste and polymer composites, (3) as grown CNTs and individual CNT and (4) CNTs arrays.
