ABSTRACT:
A flow unit for microfluidic particles separation and concentration is disclosed. The unit comprises a nozzle segment, a turn segment, and a diffuser segment. The nozzle segment is defined by a first member and a second member, and has an opening through which fluid and microfluidic particles enter. The nozzle segment has a narrowing portion at which the first and second members narrow from the opening to increase momentum of the fluid therethrough. The turn segment is defined by the first member flaring outwardly downstream from the narrowing portion to change flow direction of the fluid consistent with the first member. The diffuser segment is defined by the second member extending past the turn segment to facilitate separation of the microfluidic particles from the fluid due to the inability to follow the fluid flow.
