AC Electrokinetics

Dielectrophoresis and electrorotation are collectively referred to as AC electrokinetics. AC electrokinetics are used to study, separate, manipulate, interrogate and characterize particles on the cellular level. The term "dielectrophoreis" was coined by the late H.A. Pohl in 1951, and refers to the motion of uncharged particles in nonuniform electric fields. Dielectrophoresis can be used to levitate, separate and move particles. Electrorotation is the induced rotation of particles in an electric field, and is a method by which particles can be characterized.

Lab-on-a-Chip

Recently researchers have been investigating the concept of integrating the functionality of a laboratory into a microsystem; a "Lab-on-a-Chip". A popular method for integrating the laboratory functionality is the use of AC electrokinetics. The advantages of the Lab-on-a-Chip are cost, speed, cleanliness, increased functionality and automation. Lab-on-a-Chip applications include cell sorting, single cell analysis, rare cell detection, and water quality control.

Thesis Topic

Working with Dr. K.V.I.S Kaler and Dr. G.A. Jullien I will investigate the development of electrode structures that implement the AC electrokinetic effects, and that can be easily fabricated onto a microsystem. As well, on-chip circuitry to energize the electrodes will be developed.
