(A) Concept of the electrosmear in which the applied electric field frequency is controlled spatially, increasing from left (where the cell suspension enters) to right (where the suspension devoid of cells exits) along the slide. (B) Multifrequency signal generator used in realizing the spatial-frequency dependence. The circuit provides 36 different frequencies to excite separate groups of electrodes (shown in circle) each of which comprised 10 individual electrode elements.
