Abstract

An impedance cytometry device is described along with methods of accurately measuring particle size of particles contained in a fluid that is passed through the impedance cytometry device. The impedance cytometry device includes a substrate, and an electrode arrangement deposited on the substrate in a co-planar fashion. The electrode arrangement includes a drive electrode and a plurality of measurement electrodes located in a same plane as the drive electrode. The plurality of measurement electrodes includes at least two pairs of measurement sub-electrodes, each pair of measurement sub-electrodes including a first measurement sub-electrode positioned adjacent to the drive electrode, and a second measurement sub-electrode separated from the drive electrode by a respective first measurement sub-electrode. The impedance cytometry device may be incorporated into a substrate assembly of an electrowetting on dielectric (EWOD) device, such as in a substrate assembly containing electrowetting drive electrodes or a common reference electrode, or into a microfluidic blood counter device.
