Electrical Counting of Blood Cells (IMAGE) World Scientific Caption (a) Schematic of the biosensor used for total leukocyte and its differential counts. The inset shows the micro-fabricated coplanar electrodes aligned with the cell counting aperture of cross-section 15 µm x 15 µm. (b) Representative voltage pulses generated as the individual cells pass over the electrodes. (c) The pulse amplitude histogram shows the distinct populations of lymphocytes and granulocytes + monocytes.
