Abstract
A microfluidic valve system includes a substrate, a valve seat a compliant membrane and a mechanically actuable displacement element. The substrate includes first and second channels embedded within it and includes a first layer of material and a second layer of material. The valve seat is in fluid communication with the first and second channels. Portions of the second layer of material form sidewalls of the second channel and the valve seat. The mechanically actuable displacement element applies a mechanical force to the compliant membrane to bring the compliant membrane into sealable contact with the valve seat, thereby closing the valve system.
