Claim:
1. A microfluidic structure comprising a plurality of diaphragm valves that control fluid flow along a plurality of non-intersecting portions of microfluidic channels, wherein the plurality of diaphragm valves are configured to be actuated by a pneumatic control channel that connects the plurality of diaphragm valves together and wherein the microfluidic structure comprises a pneumatic layer comprising the pneumatic control channel and a fluidic layer comprising the plurality of non-intersecting portions of the microfluidic channels and a plurality of via holes at each of the plurality of diaphragm valves, wherein the plurality of non-intersecting portions of the microfluidic channels are in fluidic communication with an elastomer membrane sandwiched between the pneumatic layer and the fluidic layer through the plurality of via holes, and wherein applying pneumatic pressure through the pneumatic control channel actuates the plurality of diaphragm valves in parallel.
