Elution time changes due to anomalous DEP effects in microchannels under uniform and non-uniform electric fields

Sensing and Bio-Sensing Research, 2016
Conventional dielectrophoresis (DEP) force on cell and particle is altered in the proximity of the electrodes due to the failure of the dipole approximation. In these conditions an anomalous DEP (aDEP) force rules the particle manipulation.

Electrohydrodynamics and dielectrophoresis in microsystems: scaling laws [PDF]

, 2003
The movement and behaviour of particles suspended in aqueous solutions subjected to non-uniform ac electric fields is examined. The ac electric fields induce movement of polarizable particles, a phenomenon known as dielectrophoresis.

Field‐Driven Active Colloids as Distributed Micromachines: Bridging Physics, Control, and Function Across Length Scales

Advanced Science, EarlyView.
Field‐driven active colloids are framed as distributed micromachines in which externally supplied power, sensing, and control regulate task‐relevant states. By closing the loop between particle behavior, imaging, computation, and electric or magnetic actuation, these systems can progress from programmable motion toward adaptive functional outcomes ...
