1. An electrically controlled microfluidic system, comprising:

  • a microfluidic device comprising a body structure having an interior portion and at least a first exterior surface, a plurality of microscale channels disposed in the interior portion of the body structure, and a plurality of ports disposed in the body structure, communicating the exterior surface with the interior portion, each of the ports being in fluid communication with at least one of the plurality of channels;

    an electrical control system comprising a plurality of electrical leads, each of the leads being operably coupled to a power source, the electrical control system concomitantly delivering a voltage to each of the plurality of electrical leads;

    an electrical interface array comprising;

    a cover having at least a first surface, and a plurality of electrode pins mounted thereon, the electrode pins being oriented to be removably inserted into the plurality of ports, each of the electrode pins being electrically coupled to a separate one of the electrical leads the electrical interface array separately and removably coupling each of the electrical leads with each of the plurality of ports, wherein an edge of the cover is attached to the base by a hinge, whereby the cover is capable of being rotatably closed over the microfluidic device mounted on the base, to insert the plurality of pins into the plurality of ports whereupon each of the leads is in electrical communication with a fluid disposed in each of the ports.
