Abstract
A flow cell for use in a microfluidic detection system. The flow cell includes a flow cell body having a channel that extends along the flow cell body. The flow cell body has a substrate material that extends along the channel and that is transparent to at least one of excitation light or light emissions. The channel has a functionalized channel surface that includes reactive groups configured to attach to molecules for biochemical analysis. The flow cell also includes fluidic inlet and fluidic outlet ports provided on the flow cell body and an electroosmotic (EO) pump held within the flow cell body in fluid communication with the channel. The EO pump is operable to induce flow of a solution from the inlet port to the outlet port and along the functionalized channel surface.
