Abstract

See full text

A microfluidic device has a first substrate, a resilient diaphragm, an actuator, and a second substrate. The first substrate has an opening extending therethrough. The resilient diaphragm is secured to a second side and surrounds the opening. The actuator is secured to a first side and surrounds the opening. The first substrate, the resilient diaphragm, and the actuator cooperate to form a gas-tight chamber. The second substrate has a channel formed therein having a first end and a second end. The second substrate is secured to the first substrate. A volume of gas disposed in the gas-tight chamber pressurizes the gas-tight chamber and expands the resilient diaphragm such that the resilient diaphragm is disposed in the channel between the first end and the second end. The resilient diaphragm retracts from the channel to open the channel from the first end and the second when the gas-tight chamber is depressurized.
