Valve for use in microfluidic structures

A valve for use in laminated plastic microfluidic structures. The valve comprises first, second, and third layers of flexible material separated by first and second spacing layers to form microfluidic channels, and having an actuator section to selectively isolate the microfluidic channels from each...

Zusammenfassung:	A valve for use in laminated plastic microfluidic structures. The valve comprises first, second, and third layers of flexible material separated by first and second spacing layers to form microfluidic channels, and having an actuator section to selectively isolate the microfluidic channels from each other. The structure can also be used as a recirculating pump.
