Cell selective manipulation with single beam acoustical tweezers
Michael Baudoin, Jean-Louis Thomas, Roudy Al Sahely +7
Acoustical tweezers open major prospects in microbiology for cells and microorganisms contactless manipulation, organization and mechanical properties testing since they are biocom…
Folding a focalized acoustical vortex on a flat holographic transducer: miniaturized selective acoustical tweezers
Michaël Baudoin, Jean-Claude Gerbedoen, Olivier Matar +3
Acoustical tweezers based on focalized acoustical vortices hold the promise of precise contactless 3D manipulation of millimeter down to sub-micrometer particles, microorganisms an…
Orbital angular momentum transfer to stably trapped elastic particles in acoustical vortex beams
Diego Baresch, Régis Marchiano, Jean-Louis Thomas
The controlled rotation of solid particles trapped in a liquid by an ultrasonic vortex beam is observed. Single polystyrene beads, or clusters, can be trapped against gravity while…
Influence of viscosity on acoustic streaming in sessile droplets: an experimental and a numerical study with a Streaming Source Spatial Filtering (SSSF) method
Antoine Riaud, Michael Baudoin, Oliver Bou Matar +2
When an acoustic wave travels in a lossy medium such as a liquid, it progressively transfers its pseudo-momentum to the fluid, which results in a steady acoustic streaming. Remarka…
