Investigation of individual or small numbers of biological micron- and sub-micron-sized biological particles such as bacteria or viruses requires means for separation, accumulation, trapping and analysis. This may be achieved employing dielectrophoresis (DEP) in micro-fluidic systems (1-18). Since DEP relies on polarization effects, smaller particles require higher electric field strength and accordingly smaller electrode spacing in fluidic micro-systems.
