Synonyms
Dielectrophoretic force; DEP
Definition
Dielectrophoresis is the translational motion of a neutral particle by induced polarization in a nonuniform electric field. The magnitude and direction of the induced dielectrophoretic force are dependent on the characteristics of the applied electric field as well as the dielectric properties of the surrounding medium and of the particle itself.
Overview
Herbert Pohl was one of the first to study particle electrokinetics in the 1950s, particularly the manipulation of polarizable particles with nonuniform fields. He coined the term dielectrophoresis, and details of his investigations can be found in his classic text [1]. The advancement of microfabrication techniques and the demand of Lab-on-a-Chip technologies have led to the development of dielectrophoresis techniques for particulate, biological and pharmaceutical applications. Dielectrophoresis was initially used to manipulate particles and cells in the micrometer range (\(...
