“…An alternative technique is introduced by Bockrath et al 159 for single walled CNTs and then utilised in various studies [160][161][162][163][164] where CNTs have no alignment at all. Their suspension is deposited on to a substrate where coordinate markers were previously patterned.…”

The current state of solutions provided for the issue of integration between micro-and nanoscales is reviewed for the specific case of nanowires and nanotubes. Such structures serve as field emitters, transistors or laser sources, digits for manipulation and handling, as sensing elements or as agents for the modification of surface properties such as the adhesive strength. However, it is noteworthy that the majority of reported device work remains confined to component level prototype development without the prospect of full scale system integration due to the lack of batch compatible fabrication and processing techniques. On the one hand, nanostructures made by self-assembly do not possess a high level of control on their orientation and numbers, and hence, their interfacing and integration with a microsystem pose difficulties. On the other hand, top-down approaches such as manipulation, serial deposition and high resolution lithographic techniques do not satisfy the needs of large scale fabrication due to their expensive and/or nonparallel working principles. These techniques along with hybrid approaches taking advantage of the structural control of self-assembly and geometric control of high resolution lithography will be discussed and major applications will be highlighted to shed light on the capabilities and limitations associated with each process.

A fabrication method about single-walled carbon nanotube (SWCNT) network and polydimethylsiloxane (PDMS) based composite thin film is reported, which can be used as flow sensor cell. This composite thin film is immersed in deionized water and salt solution with different flow rate tests. The morphology of SWCNTs on the surface of the composite thin film is characterized by scanning electron microscopy, revealing the SWCNTs are coated by PDMS chains. The induced voltage generates along the direction of the flowing liquid and depends significantly on the ionic concentration and flow velocity. Since the SWCNTs are fixed into PDMS matrix, the I-V curves of the composite thin film before and after several flow velocity measurements are exactly coincident, and the repeating flow-induced voltage experiment shows the composite thin film has a reliable electric characteristic and wide potential of device application.

“…Using individual single walled carbon nanotubes (SWNTs) to form nanoscale contacts is an alternative approach, utilizing the small size and high electrical conductivity. In addition, standard SWNT field effect transistor (SWNT-FET) fabrication technology allows easy fabrication of these contacts [13][14][15]. Another advantage of using SWNTs is that they provide very low profile electrodes and prevent the bending of the molecule near the electrode junction.…”

We report the direct measurement of electrical transport through rod-like polymer molecules, of poly(ethyl propiolate) (PEP), utilizing single walled carbon nanotubes (SWNTs) as electrodes. The electrical properties of the devices were measured (i) before cutting a SWNT, (ii) when a SWNT was cut and (iii) after PEP deposition into the nanoscale gap in a cut SWNT. The gate-dependent electrical properties showed a reduction in current from I(on) = 2.4 x 10(-7) A for SWNT devices to I(on) = 3.6 x 10(-9) A for PEP bridge devices, both with the ON/OFF ratio of 10(4). Similarly, metallic SWNT devices showed a reduction in current from a few hundreds of microA for a SWNT device to a few nA for a PEP-SWNT structure. The current density of a single PEP molecule is 10(5)-10(6) A cm(-2), which is relatively high, indicating that the PEP molecule can carry significant current. Use of SWNT electrodes was seen to be an effective method of contacting PEP nanorods to facilitate electrical measurements.
