Micro- electrical impedance spectroscopy for particle detection
Jie Wu,Hsueh-Chia Chang +1 more
TL;DR: In this paper, a micro-electrical impedance spectroscopy detector for particle detection was proposed, and preliminary experiments were carried out using microelectrode pairs, and impedance spectra were compared with respect to opposite effects of dielectrophoresis and electrode polarization.

Dynamic polarisation of a charged colloid in an oscillating electric field
TL;DR: In this paper, the complex polarisability of a single colloidal particle under an AC electric field, where the polarisation is affected by the zeta potential of the colloid, the diffusion constant of the ions, the thickness of the electric double layer, and the frequency of the AC field, was investigated.

Determination of electrophysiological properties of human monocytes and THP-1 cells by dielectrophoresis
TL;DR: The dielectric properties for each type of cells can be used as the criteria in the development of DEP-based characterization assays and showed that THP-1 cells were physically larger than human monocytes.

Numerical modelling and measurement of cell trajectories in 3-D under the influence of dielectrophoretic and hydrodynamic forces.
TL;DR: A 3‐D microstructure micro‐milled in a cyclic olefin copolymer was designed in such a way as to assemble liver cells via insulator‐based dielectrophoresis (iDEP) in a sinusoid‐type fashion to develop a fluidic microsystem for in vitro drug testing.
Dissertation

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.
