Lire la suite >The 2D trapping and manipulation capabilities of acoustical tweezers based on focused acoustical vortices and Spiraling InterDigitated Transducers (S-IDTs) have been demonstrated both experimentally and numerically {see [Baudoin et al., Sci. Adv. 5, eaav1967 (2019)] for microparticles and [Baudoin et al., Nat. Commun., 11, 4244 (2020)] for cells}. Compared to other technologies, S-IDTs have the advantage to enable the synthesis of high-frequency vortices with trap lateral extension comparable to the cell scale (typically from 5 to 20 μm), which is a necessary condition for selectivity. However, our previous work based on the S-IDTs only demonstrated 2D trapping. Here we investigate numerically the feasibility of 3D trapping of cells and microparticles with a focused vortex beam with large aperture and axial motion of the trapped object by tuning the excitation frequency. This work opens perspectives for 3D advanced cells and microparticles manipulation.Lire moins >
