The effects of dimensionality on electrochemical sensors based on carbon nanotubes and metallic nanowires

Electrochemistry based unidimensional nanoelectrodes, such as carbon nanotubes and metallic nanowires, is now a reality that is leaving the academy and reaching a broad range of high-tech companies around the world. The intrinsic properties of electron-electron interactions, sizes and geometries significantly differentiate those nanostructures from conventional macroelectrodes or electrodes with sizes in a millimetric range. The inherent properties as well as the configuration of carbon nanotubes and metallic nanowires as electrochemical sensors are the main focus of this review. Applications and some future trends on developing of a clear pathway for assembly and integration of these into functional materials, are summarized as well.
