ABSTRACT:
An embodiment is a fluidic channel to enhance light-target interaction. A first channel portion receives a first excitation light, an analyte flow, and a sheath flow. The analyte flow and the first excitation light are separated while in the first channel portion. The sheath flow flows on two sides or surrounds the analyte flow. A second channel portion has a first redirection structure to redirect the analyte flow by the sheath flow into the first excitation light at a first detection area.
