Due to their excellent electrical

optical

mechanical properties and high aspect ratio

carbon nanotubes (CNTs) have great application potentials in energy storage

biomedicine

air and water filtration

and composites

among others. Precise and controllable positioning of CNTs between a pair of electrical conductors is the prerequisite for many of their applications. As a promising way

dielectrophoresis (DEP) has been frequently used for this purpose. This paper introduces the theory of DEP and analyzes the effect of DEP parameters on the results of CNT assembly. The research progress on DEP control with respect to the position and quantity of assembled CNTs has been reviewed.
