Abstract:
1. A microfluidic device comprising: a body structure comprising first and second microchannels, the microchannels intersecting at a first intersection, the body structure further comprising a plurality of reservoirs, the plurality of reservoirs comprising first, second, third, and fourth sample reservoirs and first, second, and third waste reservoirs, the plurality of reservoirs comprising a total of at least 8 reservoirs disposed on a first surface of the body structure, wherein each sample reservoir is fluidly connected to the first intersection by a substantially equal fluid path, wherein each sample reservoir is fluidly connected to the first waste reservoirs through a fluid path comprising the first microchannel, and wherein each sample reservoir is fluidly connected to one of the second or the third waste reservoirs through only on fluid path, wherein said one fluid path does not comprise the first microchannel; and a detector that detects one or more analytes in the first microchannel.
