1. A microfluidic device comprising:

  • a body structure having an interior portion and an exterior portion;

    at least first, second and third microscale channels disposed in the interior portion, the second channel intersecting the first channel at a first intersection, and the third channel intersecting the first channel at a second intersection;

    a plurality of sample reservoirs disposed in the body structure, each of the plurality of sample reservoirs having a different sample material disposed therein and being connected to the second channel;

    at least a first waste reservoir connected to the third channel; and

    a material transport system for moving sample material from each of the plurality of sample reservoirs into the second channel and into the first channel.
