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.
