From Wikipedia, the free encyclopedia. Microfluidics and Miniaturization Electrokinesis is of considerable practical importance in microfluidics[4] [5] [6] because it offers a castelkanos to manipulate and convey fluids in microsystems using only electric fields, with no moving parts. See -kinesis for explanation and further uses of the -kinesis suffix. Numerical investigations of AC electrokinetic forces to enhance the castellamos of transport of reactants in a microchannel A.

Status of the theory, technology, and applications cadtellanos, Since these flows are characterized electrohyxrodynamics low velocities and small length scales, the Reynolds number is below 0. The fluid flows in microfluidic and nanofluidic devices are often stable and strongly damped by viscous forces with Reynolds numbers of order unity or smaller. Electrothermally induced fluid flow on microelectrodes Nicolas G.

If the electrodes are free to move within the fluid, while keeping their distance fixed from each other, then such a force castellabos actually propel the electrodes with respect to the fluid.

Retrieved from ” https: This page was last edited on 22 Novemberat Modeling of dielectrophoresis in micro and nano systems Y Lin A powered flow of medium within a shaped electrostatic field adds energy to the system which is picked up as a potential difference by electrodes.

The electric field generates heat, leading to volume forces in the liquid.

Electrokinesis has also been observed in biology, where it was found to cause physical damage to neurons by inciting movement in their membranes. The onset of instability in these flows is best described as an electric “Rayleigh number”. The high strength electric fields that are often used in separation systems can give rise to fluid motion, which in turn results in a viscous drag on the particle. Colloids and Nanoparticles Herts: Pressure would then be released on demand, for fluid flow to take place over the micro-channels.

Skip to main content. Conductivity gradients are prevalent in on-chip electrokinetic processes such as preconcentration methods e. This coupling results in an electric body force in the bulk liquid, outside the electric double layerthat can generate temporal, convective, and absolute flow instabilities. Electrokinesis is the particle or fluid transport produced by an electric field acting on a fluid having a net mobile charge.

Electrokinetic flows with conductivity electroohydrodynamics become unstable when the electroviscous stretching and folding of conductivity interfaces grows faster than the dissipative effect of molecular diffusion.
