1. An analytical system comprising:

  • a sample substrate having a plurality of mesoscale channels disposed therein, the plurality of channels connecting a plurality of reservoirs, each of the plurality of channels having at least one cross-sectional dimension between about 0.1 and 500 μ

    m;

    a base unit comprising an electrical power supply;

    a sample substrate interface array attached to the base unit and comprising;

    a sample substrate attachment region including a plurality of electrical connectors disposed thereon, the electrical connectors being electrically coupled to the electrical power supply and being positioned within the substrate attachment region to provide electrical connection between the plurality of reservoirs and the electrical power supply when the substrate is placed, in the substrate attachment region wherein the electrical connectors comprise pin electrodes disposed on the interface array, the pin electrodes being positioned to directly engage fluids present in the reservoirs; and

    an energy emission detector disposed in the base unit and positioned to detect energy emitted from at least one of the channels disposed in the sample substrate, when the sample substrate is placed in the sample substrate attachment region.
