TLDR
A 2D model of different shapes of traveling wave microelectrodes array based on printed circuit board (PCB) technology is presented and discussed to reach the efficient design of twDEP microelectROdes.Abstract:
The movement of uncharged polarizable particles towards the location of extreme field strength in a non-uniform electric field is known as Dielectrophoresis phenomena. A traveling wave dielectrophoresis (twDEP) is an effective technique for particle manipulation and separation of biological particles. The twDEP is an electro-kinetic method resultant of the interaction between a non-uniform electric field and polarizable particles. The proposed twDEP is used to manipulate microbeads. The model of twDEP platform and polarizable particles (microbeads) in addition to the twDEP force which is a resultant of the interaction of a non-uniform electric field and polarizable particles were simulated using COMSOL Multiphysics ®. In this work, a 2D model of different shapes of traveling wave microelectrodes array based on printed circuit board (PCB) technology is presented and discussed to reach the efficient design of twDEP microelectrodes.read more

Enhancing traveling-wave dielectrophoresis with signal superposition
TL;DR: In this approach termed superposition-TWD (travelling-wave dielectrophoresis), one or more DEP and TWD signals are applied together to change the levitation height of the particles above the electrode plane, and in so doing to alter the range of frequencies over which TWD occurs.
