1D dynamic patterning of fluorescent polystyrene beads. Left: the optical images of the 1D tunable patterning device. The microchannel covers two lines of the pressure nodes of the SSAW. Right: I, II, and III show the 1D pattern at the frequencies of 12 MHz, 15 MHz, and 18 MHz, respectively. The period in region I, II, and III is 150 µm, 120 µm, and 100 µm, respectively.
