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…
Acoustic confinement in superlattice cavities
Daniel Garcia-Sanchez, Samuel Déleglise, Jean-Louis Thomas +3
The large coupling rate between the acoustic and optical fields confined in GaAs/AlAs superlattice cavities makes them appealing systems for cavity optomechanics. We have developed…
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…
SAW synthesis with IDTs array and the inverse filter: toward a versatile SAW toolbox for microfluidics and biological applications
Antoine Riaud, Michael Baudoin, Jean-Louis Thomas +1
Surface acoustic waves (SAWs) are versatile tools to manipulate fluids at small scales for microfluidics and bio- logical applications. A non-exhaustive list of operations that can…
Taming the degeneration of Bessel beams at anisotropic-isotropic interface: toward 3D control of confined vortical waves
Antoine Riaud, Jean-Louis Thomas, Michael Baudoin +1
Despite their self-reconstruction properties in heterogeneous media, Bessel beams are known to degenerate when they are refracted from an isotropic to an anisotropic medium. In thi…
Synthesis of anisotropic swirling surface acoustic waves by inverse filter, towards integrated generators of acoustical vortices
Antoine Riaud, Jean-Louis Thomas, Eric Charron +3
From radio-electronics signal analysis to biological samples actuation, surface acoustic waves (SAW) are involved in a multitude of modern devices. Despite this versatility, SAW tr…
Observation of a single-beam gradient force acoustical trap for elastic particles: acoustical tweezers
Diego Baresch, Jean-Louis Thomas, Régis Marchiano
We demonstrate the trapping of elastic particles by the large gradient force of a single acoustical beam in three dimensions. Acoustical tweezers can push, pull and accurately cont…
Cyclones and attractive streaming generated by acoustical vortices
Antoine Riaud, Michael Baudoin, Jean-Louis Thomas +1
Acoustical and optical vortices have attracted large interest due to their ability in capturing and manipulating particles with the use of the radiation pressure. Here we show that…
