Abstract

In this work we designed and fabricated an improved inertial focusing chip based on the combination of Dean flow and geometry-induced secondary flow to enhance the total secondary flow. Our design resulted in the device with channel length of 25 mm and chip area of less than 200 mm2, smaller than most of the passive focusing devices reported so far. We used fluorescent particles with diameter of 10.7 μm to test the focusing performance of the device and achieved a focusing width of only 11.5 μm.
