Abstract:
A microfluidic device comprising:(a) an electronic component comprising a substrate having a surface, a layer of electrically-conductive material deposited on a portion of the substrate surface, and a layer of insulating material deposited on the layer of electrically-conductive material and the substrate surface, wherein the layer of insulating material has a substantially planar surface opposite the substrate surface; and (b) a fluid-handling component having a contoured first surface and a second surface opposite the contoured first surface, wherein the contoured first surface of the fluid-handling component is affixed to the layer of insulating material on the electronic component, thereby forming one or a plurality of cavities between the electronic component and the fluid-handling component, and wherein the electrically-conductive material is in electrical or thermal communication with said cavities formed between the electronic component and the fluid handing component.
