The HeLa cell's motion is further presented in Supporting Information SV-2. Please note that, in contrast to many solid microstructures used for acoustic manipulation, 31 the demonstrated rotational motion has been achieved at a low excitation voltage of 6 V PP , thereby preventing possible damage to the sample due to high power pressure fields. The successful manipulation of the HeLa cell is based on the combination of the acoustic radiation force and acoustic streaming. As demonstrated through the numerical simulations, the Gor'kov potential (see Figure ) ) leads to a force which pushes biological specimens towards the embedded microbubble. Once trapped, the single cell is rotated via the viscosity-related acoustic streaming, which allows for the visual investigation of the specimens intracellular components as well as individual features of the cell membrane. Please note that the wall thickness appears larger in the image sequence due to the plane of focus being set on the specimen.
