FIG. 2.

(a) The worm responder (WR) of the microfluidic device, which is composed of excitation electrode, receiving electrode and other auxiliary equipment. The two ITO electrodes of each worm responder are 0.8-mm wide, 1350 Å ± 150 Å in thickness with 0.8 mm spacing which are embedded under the cross-sectional area of T-shape micro channel. An optimal voltage signal (80 kHz at 30 Vpp) is applied to the excitation electrode. Worms are driven through the measurement area one by one at the flow rate of 5 μl min−1. (b) The schematic diagram of the voltage profile. Four peaks correspond to 4 worms passing through the measurement zone serially.
