n. (context physics English) The exertion of a force on a (uncharged) particle in a non-uniform electric field
Wikipedia
Dielectrophoresis (or DEP) is a phenomenon in which a force is exerted on a dielectric particle when it is subjected to a non-uniform electric field. This force does not require the particle to be charged. All particles exhibit dielectrophoretic activity in the presence of electric fields. However, the strength of the force depends strongly on the medium and particles' electrical properties, on the particles' shape and size, as well as on the frequency of the electric field. Consequently, fields of a particular frequency can manipulate particles with great selectivity. This has allowed, for example, the separation of cells or the orientation and manipulation of nanoparticles and nanowires. Furthermore, a study of the change in DEP force as a function of frequency can allow the electrical (or electrophysiological in the case of cells) properties of the particle to be elucidated.
Usage examples of "dielectrophoresis".
The mixers and movers in the miniature factories used a phenomenon called dielectrophoresis to harness the small electrical charges generated by every living thing.
These wafers are miniature factories that measure dielectrophoresis, the minute electrical charges generated by all living creatures.
