Lab-on-a-chip BioMEMS devices have developed in recent years as a way to rapidly perform total biological analysis. With the complexity of fabrication of mechanical parts in microfluidic devices comes the desire to create devices which use alternative methods of pumping, mixing and manipulating fluids and suspended microparticles for reactions - such as electrokinetics. This paper presents novel ways of fabricating electrokinetic devices, which use the phenomenon of dielectrophoresis (DEP) for manipulation of suspended microparticles. Affects of driving waveforms are investigated. Visual results from microparticles are used to show the effect of operation of electrokinetic devices. Improved device designs and device operation are discussed.
