Patent ID: 8101428

Claim:
A method of use for a modular, reconfigurable microfluidic system, comprising: providing a microfluidic system including: a modular first microfluidic chip having a given configuration of microfeatures including a plurality of valves, each of which is actuated by a pneumatic signal, wherein said given configuration corresponds to a given application; a separate, replaceable, modular first chip manifold having a plurality of pneumatic ports on an underside thereof and a plurality of pneumatic channels disposed therein, which are in fluid connection with both the plurality of valves and the plurality of pneumatic ports, wherein said plurality of pneumatic ports have a fixed configuration, and said plurality of pneumatic channels have a given configuration specifically corresponding to the given configuration of the plurality of valves; and a separate, modular pneumatic manifold having a plurality of apertures that provide a passage of pneumatic signals therethrough, in fluid connection with said plurality of pneumatic ports, wherein said plurality of apertures have a fixed configuration specifically corresponding to the fixed configuration of the plurality of pneumatic ports of the chip manifold; using the modular, reconfigurable microfluidic system for a different given application, further comprising: replacing the modular first microfluidic chip with at least a modular second microfluidic chip having a different given configuration of microfeatures including a plurality of valves wherein said different given configuration corresponds to the different given application; replacing the modular first chip manifold with at least a modular second chip manifold having a plurality of only pneumatic ports on an underside thereof and a plurality of only pneumatic channels disposed therein and in fluid connection with the plurality of pneumatic ports, wherein said plurality of pneumatic ports have a fixed configuration, and said plurality of pneumatic channels have a different given configuration specifically corresponding to the different given configuration of the plurality of valves of the at least the second microfluidic chip; removably connecting the modular pneumatic manifold to the modular at least the second chip manifold; and transmitting, via the pneumatic manifold, a pneumatic signal to the chip manifold and routing, via the chip manifold, the pneumatic signal to at least one of the plurality of valves and actuating, via the pneumatic signal, the at least one valve to transport a fluid through the microfluidic chip; and transporting and reacting fluidic reagents in the microfluidic chip.
