Dielectrophoretic isolation of cells using 3D microelectrodes featuring castellated blocks
Xiaoxing Xing,Levent Yobas +1 more
TL;DR: These electrodes provide a more effective dielectrophoretic force field than thin-film surface electrodes and yet immobilize cells near stagnation points across a parabolic flow profile for enhanced cell viability and separation efficiency.

Floating electrode dielectrophoresis.
TL;DR: Electrically floating electrodes are used in DEP devices and it is demonstrated that effective DEP forces can be achieved by using floating electrodes, which is expected to promote the use ofDEP devices in the manipulation of nanoparticles.

Separation of sub-micron particles from micron particles using acoustic fluid relocation combined with acoustophoresis.
TL;DR: By combining acoustic fluid relocation with acoustophoresis, sub-micron particles can be effectively separated from micron particles at high flow rates and it can be further implemented to separate binary mixtures of micron particle if the volumetric ratio of two particles is greater than 10 and the larger particle diameter is about 10 μm.

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.
