Modeling dielectrophoretic force for manipulating carbon nanotubes (CNTs)
TL;DR: In this article, a new mathematical model for dielectrophoretic for applied to nanotubes has been developed, which can significantly improve the separation of semiconducting and metallic band structure carbon nanitubes, ultimately providing a critical and major step towards the use of carbon nanotube in the manufacturing of electronics and sensors for potential use in electrical circuits.

A Programmable Biochip for the Applications of Trapping and Adaptive Multisorting Using Dielectrophoresis Array
TL;DR: In this paper, movable beads are used as the mobile probes to capture the target protein molecules, and an array of micropyramid DEP traps with a good levitation control on the height of the beads is located at the upstream to enhance the hybridization function of the mobile probe.
Journal ArticleDOI
Charge-Based Separation of Micro- and Nanoparticles.
TL;DR: The enhanced displacement effect due to electrokinetic charge is found to be significant at low frequency and for particles with high zeta potential, suggesting that it is associated with either non-linear electrokinetics or dielectrophoresis (DEP), but since large changes in separation behavior over the frequency range at which DEP forces are expected to remain constant, DEP can be ruled out.

Ac electrokinetics: a review of forces in microelectrode structures
TL;DR: In this article, the frequency dependency and magnitude of electrothermally induced fluid flow are discussed for low frequencies (up to 500 kHz) and the effects of Brownian motion, diffusion and buoyancy force are discussed in the context of the controlled manipulation of sub-micrometre particles.

The Motion and Precipitation of Suspensoids in Divergent Electric Fields
TL;DR: In this article, it was shown that the phenomena of dielectrophoresis and dielectro-precipitation can be observed under rather ideal conditions, though it is ordinarily often difficult to do so because of the presence of the more easily produced electrophoreis or ion-type migration of charged particles.
