Patent Number: 7,611,673

Title: PMDS microfluidic components and methods of operation of the same

Abstract: Component microfluidic devices which are integrated with polydimethylsiloxane (PDMS) microfluidic chips, include designs for an electrical and optical pressure gauge, valve, electrostatic and magnetic pumps, alternating or mixing pumps, a solenoid, a magnetometer, a magnetically actuated reversible filter and valve, and a hydrolysis valve. These devices enhance and miniaturize microfluidic control, thereby expanding the available capabilities and allowing complete system miniaturization for handheld diagnostic apparatuses.
