Acoustic Levitation and Acoustic Sorting

Acoustic manipulation of particles or living cells in micro-cavities and micro-channels

Acoustophoresis of particles (with M. Hoyos and former Ph. D. student O. Dron)


Principle of the acoustic focusing of particles in suspension in a micro-cavity or a micro-channel.

Movie showing the focusing of the particles at mid-height of the channel: focusing_crop (converti)

We also demonstrated that it is possible to move the sheet of particles along the height of the channel by varying the acoustic frequency:


This discovery allows many applications which have been patented worlwide by the CNRS.
