The selection, manipulation and positioning of individual cells (or microorganisms) opens up unprecedented prospects for studying their behavior, interactions, and response to mechanical stress (mechanotransduction) or for organizing them with a view to tissue engineering.
Researchers at the IEMN in collaboration with a researcher from the INSP have demonstrated that it is possible to use ultrasonic vortices to trap and manipulate individual cells with greater forces than their optical counterparts, without damaging them. These acoustic vortices are synthesized using holographic electrodes deposited on the surface of a piezoelectrically active material.
