چکیده
This paper provides a concise review on the recent development of nanoscale hybrid systems based on carbon nanotubes (CNTs) for biological sensing and control. CNT-based hybrid systems have been intensively studied for versatile applications of biological interfaces such as sensing, cell therapy and tissue regeneration. Recent advances in nanobiotechnology not only enable the fabrication of highly sensitive biosensors at nanoscale but also allow the applications in the controls of cell growth and differentiation. This review describes the fabrication methods of such CNT-based hybrid systems and their applications in biosensing and cell controls.

ABSTRACT In this work, we have prepared film sensor elements based on a hybrid system poly(3,4-ethylenedioxythiophene)-porous silicon nanocrystals-carbon nanotubes on flexible polymer substrates. Our FTIR spectroscopy-based studies for the molecular structure of the materials obtained suggest some interaction of their components in the hybrid layer. The influence of adsorption of water molecule...

We report an ultrafast and sensitive hydrogen (H(2)) sensing platform using semiconducting single-walled carbon nanotubes (SWCNTs) decorated with tin oxide (SnO(2)) nanocrystals (NCs). The hybrid SnO(2) NC-SWCNT platform shows a response time of 2-3 seconds to 1% H(2) under room temperature and can fully recover within a few minutes in air.

The separation of two different types of multi-walled carbon nanotubes is studied in a dielectrophoresis-based microchannel system in seven different solvents as the suspending medium. A simple model was developed to predict the behavior of the multi-walled carbon nanotubes in the above mentioned system. Then, the equations of motion for the multi-walled carbon nanotubes in that system were in...
