Leti has developed an acousto-microfluidic technology which manipulates micro- and nanoscale samples with evanescent sound waves. The technique is envisioned to replace existing technology, which uses high-frequency propagative surface acoustic waves (leaky SAW) to move microscopic samples on complex substrates. The technique generates an evanescent Bessel beam in the low-frequency ultrasound (kHz) range. Thanks to the enhanced radiation force ...
