Claim 8:
9. A microfluidic device, comprising:
a substrate;
a lid mounted to the substrate and forming a discrete microfluidic chamber between structures including an interior surface of the lid and a portion of the substrate, said lid comprising an inlet and a vent positioned relative to one another to facilitate loading of a fluid to the discrete microfluidic chamber via capillary action; and
an elongated microchip mounted to the substrate, a portion of the elongated microchip positioned within the discrete microfluidic chamber and a second portion of the elongated microchip positioned outside of the discrete microfluidic chamber, wherein the elongated microchip has a width to length aspect ratio from 1:10 to 1:150;
wherein the lid further comprises an exterior surface modification selected from a Fresnel lens, a crenulated surface, a non-uniform thickness, a thin film optical filter, and a combination thereof.
