Oriented CNT Electrodes

Oriented CNT self-assembly route The self assembly approach relies on the alignment of short SWNTs that were cut by oxidative treatments and ultrasonication [43, 

121-126]. The main issue to control is the length of the cut CNT that should be quite homogeneous for guaranteeing a well-ordered assembly.

Other groups have achieved CNT forest assemblies by electrostatic SWNT-COO / Fe interactions also starting with shortened CNTs. The assembly process involves sequential substrate dipping in dilute Nafion and aqueous FeCl3 solutions followed by DMF-assisted precipitation of the nafion-adsorbed Fe to produce thin FeO(OH)/FeOCl nanocrystals. Subsequent immersion into a DMF disperse nanotube suspension produces the forest assembly that is driven by acid-base neutralization [12, 61, 121[. 

The silicon substrate constitutes a very interesting support for facilitating the integration in microelectronic devices. The electrochemical and electroanalytical fields can gain remarkable benefits from the silicon-based miniaturization devices, especially if arrays of metal electrodes can be fabricated. An understanding of the electrochemical properties of CNTs directly attached to silicon is thus essential for their potential application in developing silicon-based electrochemical or (bio)electrochemical
