Nanotubes applications

Many of the carbon nanotube applications presently under consideration relate to multi-wall carbon nanotubes, partly because of their greater availability, and because the applications do not explicitly depend on the ID quantum effects associated with the small diameter single-wall carbon nanotubes.

While this sensor was the first instance of a SWNT-based optical sensor and a step forward in nanotube applications, the sensor does have some disadvantages. First and foremost, the sensor would operate as an optical analogue of a flux-based sensor in any in vivo setting by using a glucose-limiting membrane and as such suffers from the same drawbacks of those sensors mentioned earlier. The sensor also has a limited lifetime, as the ferricyanide is a limited resource, and will eventually be used to completion. Finally, the sensor is not regenerable and would need to be completely replaced after its lifetime has been reached. 

Atomic force microscopy [6, 7] is one of the most suitable methods for research carbon nanotubes. AFM allows to receive not only a relief of the studied sample, but also distribution of mechanical characteristics, electric, magnetic and other properties on its surface. With the help of AFM, controllable manipulation of individual CNTs and CNTs bundles became possible. In this paper we report our approach to manipulating SWCNTs bundles with lateral force microscopy. LFM gives possibility to study lateral forces that probe acts upon bundles. In spite of good visualization of LFM, its lack is absence of reliable techniques of quantitative interpretation of results. The new way of calibration developed ourselves has allowed to pass from qualitative estimations to quantitative investigations [8], The given calibration technique is much more exact, than others known till now [9, 10], and does not assume simplification. With the help of new technique we may study adhesion of bundles to substrate and adhesion of CNTs in bundle qualitatively in real time more easy way. This result will provide new possibilities for nanotube application.

The fabrication of supercapacitors and electrochemical actuators that could be used as artificial muscles is another alternative for nanotube applications. Supercapacitors already were built on hybrid vehicles because this could provide rapid acceleration and store braking energy electrically. When using sheet electrodes with SWNT and MWNTs, it is possible to obtain specific capacitance of 180 and 102 F/g and power densities of 20 and 8kW/kg, respectively.
