Abstract
A microfluidic device includes a plurality of first flow channels and a plurality of second flow channels, each such second flow channel intersecting multiple of the first flow channels to define intersecting volumes and a plurality of looped flow channels that each include segments of the flow channels between the intersecting volumes to define a closed loop. The microfluidic device also includes a plurality of control valves each such control valve having a control channel and a deformable segment disposed to restrict flow through a respective one of the first and second flow channels in response to an actuation force applied to the control channel to deflect the deformable segment. The microfluidic device further includes a pump operatively disposed to regulate flow through one of the looped flow channels to regulate flow by the recirculating pump.
