1. A microfluidic device, comprising:
a base component defining at least a portion of a first channel of the microfluidic device;
a cap component comprising a sealing lip extending a first distance from a first side of the cap component and a support portion extending a second distance, less than the first distance, from the first side of the cap component; and
a polymer material filling at least a portion of a cavity defined by the base component, the support portion of the cap component, and the sealing lip of the cap component, wherein the cavity is sealed from the first channel of the microfluidic device by the sealing lip of the cap component,
wherein the polymer material is injection molded to fill the cavity and cured to secure the base component to the cap component.
