Methods and systems for moving fluid in a microfluidic device
First Claim
1. A microfluidic device, comprising:
- a first gas actuator to provide a gas pressure sufficient to move first sample material between first and second spaced apart locations of the microfluidic device;
a second gas actuator to provide a gas pressure to move second sample material between third and fourth spaced apart locations of the microfluidic device, the second gas actuator being spaced apart from the first gas actuator.

Abstract
The present invention relates to a system and method for moving samples, such as fluid, within a microfluidic system using a plurality of gas actuators for applying pressure at different locations within the microfluidic. The system includes a substrate which forms a fluid network through which fluid flows, and a plurality of gas actuators integral with the substrate. One such gas actuator is coupled to the network at a first location for providing gas pressure to move a microfluidic sample within the network. Another gas actuator is coupled to the network at a second location for providing gas pressure to further move at least a portion of the microfluidic sample within the network. A valve is coupled to the microfluidic network so that, when the valve is closed, it substantially isolates the second gas actuator from the first gas actuator.
