Scientists have demonstrated an innovative method for manipulating the rotation of microparticles and small-scale living organisms, such as zebrafish larvae, using bulk acoustic waves (BAW) with orthogonal phases. This technique enables precise, on-demand control of rotational movement, opening new avenues for studying biological processes and manipulating materials at the microscale. The advance is based on the application of acoustic fields that generate torques on objects, allowing them to rotate in a specific plane.
