    Abstract: A microfluidic check valve and a method of using the check valve In microfluidic devices includes a check valve comprising two stacked chambers that are separated by a pore-containing membrane. The membrane is composed of an elastomeric material and can be configured in normally open or normally closed state. The normally open check valve can be implemented so that the degree of back pressure necessary to close the valve can be set.

    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.
