Abstract
A flow cell for use in a microfluidic detection system is provided. The flow cell includes a flow cell body having a channel that is configured to convey a solution through the flow cell body. The flow cell also includes a bottom surface and a top surface. The bottom surface is configured to be removably held by the detection system, and the top surface is transparent and permits light to pass therethrough. The flow cell body also includes fluidic inlet and outlet ports that are in fluid communication with the channel. A pump cavity is also provided in the flow cell body. The pump cavity fluidly communicates with, and is interposed between, an end of the channel and one of the fluidic inlet and outlet ports. An electroosmotic (EO) pump is held in the pump cavity. The EO pump induces flow of the solution through the EO pump and channel between the fluidic inlet and outlet ports.
