Fig. 1. Microfluidic device and experimental setup for screening the electric-induced response of semi-immobilized 5-7dpf zebrafish larva. (A) The experimental set up made up of a microscope, two syringe pumps, sourcemeter, computer, camera and microfluidic device connected via tubing and wires (B) The device consisting of a sloped inlet, rounded side channels, main channel, trapping region (TR), screening pool, outlet, two electrodes and valve channel. (C) Close up view of the TR and screening pool showing a semi-immobilized 5dpf larva.
