Abstract
The present disclosure relates to method, system for microfluidic control. One or more embodiments of the disclosure relate to pneumatically actuated 'lifting gate' microvalves and pumps. In some embodiments, a microfluidic control module is provided, which comprises a plurality of pneumatic channels and a plurality of lifting gate valves configured to be detachably affixed to a substrate. The plurality of lifting gate valves are aligned with at least one fluidic channel on the substrate when affixed to the substrate. Each of the valves comprises: a pneumatic layer, a fluidic layer, and a pneumatic displacement chamber between the pneumatic layer and the fluidic layer. The fluidic layer has a first side facing the pneumatic layer and a second side facing away from the pneumatic layer, wherein the second side has a protruding gate configured to obstruct a flow of the fluidic channel when the fluidic layer is at a resting state.
