Figure 5.
Acoustofluidic-based, contactless actuation and selection of a 5-day post-fertilization (dpf) zebrafish larvae. Red squares indicate the excited IDTs at the 1st stage. Blue squares indicate the excited IDTs at the 2nd stage. The zebrafish larva was moved to the left, middle, or right following the configurations of IDT excitation shown in (a), (b), or (c), respectively. The dots indicate the position of the larvae otic vesicles. The dot-to-dot interval was 400 ms. The arrows indicate the directions of larva translation. Power: 28 dBm. Frequency: 24.2 MHz. Scale bars: 5 mm.
