Recent progress in the development of microelectrode structures has led to new techniques for the dielectrophoretic characterization and sorting of cells, microorganisms and other bio-particles using non-uniform AC electric fields. Applications of dielectrophoresis have included the selective spatial manipulation and separation of mixtures of bacteria, viable and unviable cells, cancerous and normal cells, and red and white blood cells. SIBlab is conducting research on the dielectrophoretic phenomena using microfluidic techniques to separate, sort and amplify DNA mixtures/strands, microorganisms and other biomolecules.
