Experimental and modeling validation on the effectiveness of the control valves. (a) Images of fluorescent microspheres in the main channel with microfluidic control valve actuation from 0 to 30 psi and then back to 0 psi (scale bar is 40 μm). (b) Images and COMSOL simulation of fluid streamlines through the trapping chambers and the micropipette channel when the control valves are at 0 psi and 30 psi (scale bar is 40 μm).
