Acoustical tweezers for contactless and selective manipulation of micro- and nanoscopic objects
This MicroElectroMechanical System (MEMS) allows the remote manipulation of particles, cells and droplets lying in a liquid sample with a high selectivity (one particle can be selected and moved in dependently of its neighbors).
This technology relies on the use of a specific kind of volume acoustic waves called swirling volume acoustic waves, which are synthesized few millimeters from piezoelectric material with Interdigitated transducers.
These waves once transmitted to a liquid sample create a localized acoustical trap.
