The precise placement of single-walled carbon nanotubes (SWNTs) in device configurations has been accomplished by AC dielectrophoresis using a biomimetic surfactant, dioctyl sodium sulfosuccinate (i.e. AOT) dispersed SWNTs. To better serve the utilization of SWNTs/AOT for device fabrication, the dispersion of SWNTs in AOT aqueous solutions was investigated at different micellar concentrations and compared with other surfactants. UV-Vis-NIR spectroscopy and AFM microscopy have been employed to characterize solubilized individual SWNTs. Additionally, dispersed solution has been utilized to align SWNTs in field-effect transistor geometrics. We have ascertained that the AOT isolated individual tubes, well-protected from breakdown during sonication, are good candidates for device applications. 2007 Elsevier B.V. All rights reserved.
