Dielectrophoresis can be used to manipulate, transport, separate and sort different types of particles. Since biological cells have dielectric properties, dielectrophoresis has many medical applications. Instruments that separate cancer cells from healthy cells have been made. Platelets have been … See more Dielectrophoresis (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 … See more Electrode geometries At the start, electrodes were made mainly from wires or metal sheets. Nowadays, the electric field in DEP is created by means of electrodes which minimize the magnitude of the voltage needed. This has been possible … See more • AES Electrophoresis Society - Learning Center • Biological cell separation using dielectrophoresis in a microfluidic device See more Although the phenomenon we now call dielectrophoresis was described in passing as far back as the early 20th century, it was only subject to serious study, named and … See more The simplest theoretical model is that of a homogeneous sphere surrounded by a conducting dielectric medium. For a homogeneous … See more • Turcu, I; Lucaciu, C M (1989). "Dielectrophoresis: a spherical shell model".
