1. A microfluidic device, comprising:

  • a body structure having at least a first microscale channel disposed therein;

    a capillary element having first and second ends and a capillary channel disposed therethrough, the first end of the capillary element being attached to the body structure whereby the capillary channel is in fluid communication with the at least first microscale channel; and

    a conductive layer deposited on at least a portion of a surface of the capillary element, the conductive layer extending from a point proximal to the first end of the capillary element up to the second end of the capillary element, wherein the capillary element is attached to the body structure by the first end being inserted into an aperture in the body structure.
