Реферат: A method of performing an acoustofluidic operation, comprising the steps of: a. providing (1) an acoustofluidic device (10) comprising: - a substrate (12) in which a microfluidic cavity (30) is positioned, and - at least a first (50a) and a second (50b) ultrasound transducer (50), each provided in acoustic contact with the substrate (12) for transferring ultrasonic vibrations to the substrate and causing the substrate to vibrate, wherein the first and the second ultrasound transducers each comprise a first electrode (52) and a second electrode (56a, 56b) in contact with a piezoelectric or electrostrictive material (54), and wherein the first electrodes are in electric contact with each other, b. providing a fluid, such as a liquid (2) or liquid suspension in the microfluidic cavity (30), c. applying (56a, 56b) of the first and second ultrasound transducers (50a, 50b), wherein the drive signal has a frequency f that corresponds to an acoustic resonance peak of one or more of the substrate, the microfluidic cavity filled with a fluid, and the transducers (50a, 50b), and d. letting the electrical potential of the first electrodes (52) float.
