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.

Review Article—Dielectrophoresis: Status of the theory, technology, and applications
TL;DR: Current trends suggest that the theory and technology have matured sufficiently for most effort to now be directed towards applying DEP to unmet needs in such areas as biosensors, cell therapeutics, drug discovery, medical diagnostics, microfluidics, nanoassembly, and particle filtration.

Separation of Submicron Bioparticles by Dielectrophoresis
TL;DR: With electrode arrays fabricated using direct write electron beam lithography, it is shown that different types of submicron latex spheres can be spatially separated and it is demonstrated that tobacco mosaic virus and herpes simplex virus can be manipulated and spatially separation in a microelectrode array.

Separation of viable and non-viable yeast using dielectrophoresis
TL;DR: Dielectrophoresis, the movement of particles in non-uniform AC electric fields, was used to rapidly separate viable and non-viable yeast cells with good efficiency and cell viability was not affected by the separation procedure.
Journal ArticleDOI
Dielectrophoretic characterization and separation of micro-organisms
TL;DR: The effective electrical conductivity values for a variety of Gram-negative and positive bacteria have been determined and experimental conditions were selected where micro-organisms of different species can be separated using dielectrophoresis - the movement of particles induced by non-uniform AC electric fields.
