N2 - The electrical properties of particle solutions can be investigated on a single particle basis by using micro fluidic channels. The impedance can be measured across the channel using at least one pair of conductive electrodes, at least one electrode of a pair being a fingered electrode having a plurality of fingers. The pattern of fingered electrodes creates a longer and more complicated measurement signal shape which leads to a significant improvement of measurement sensitivity. An application for the proposed technology is to significantly improve the measurement sensitivity of impedance measurements on blood cells, leading to a better differentiation between different types of white blood cells. Better measurement sensitivity also enables the measurement of smaller particles and higher throughput.
