Focusing of live cells by the microfluidic device with fs laser patterned arrays of open v-shaped microstructures. The lateral positions of (a) Jurkat cells, (b) PC 12 cells and (c) MDCK cells at the inlet and outlet are recorded and compared, when the flow rate is 180 nL/min. Superimposed experimental images of cell distribution are presented. Red dotted circles denote cells. Scale bar is 20 µm. 200 cells are measured for each group.
