Precise manipulation capabilities at small scales are of increasing importance for a wide variety of research fields such as biomedicine or biology, e.g., for the investigation of morphogenesis through single-cell analysis or detailed 3D reconstruction of complex model organisms. Therefore, it is not surprising that a large number of techniques have been introduced to facilitate the controlled rotation of small particles based on mechanical, magnetic, electrical, hydrodynamic, and optical forces. Unfortunately, many of these techniques rely on specific properties of the specimen, which significantly reduces their applicability for biological samples. The controlled particle manipulation using acoustic forces, acoustophoresis, has been widely applied due to its advantages of being label-free, contactless, and flexible in design while exposing biocompatible behaviour. Recent publications have illustrated a large variety of microstructures suitable for the controlled manipulation of single cells and particles through acoustic forces. Solid features such as polydimethylsiloxane (PDMS) or silicon sharp-edges are acoustically excited via an external piezoelectric transducer, leading to the formation of acoustic streaming patterns in the nearby liquid. Unfortunately, the majority of these acoustofluidic setups require a high input power to generate acoustic fields that are strong enough to manipulate the specimens, which might damage biological samples. Additionally, depending on their design and arrangement, hydrophilic surface coatings are required to prevent the unintended formation of air bubbles which otherwise significantly alter the anticipated streaming patterns. Furthermore, most solid-feature-based designs are limited to the generation of in-plane vortices and are, therefore, unable to provide additional visual insights through the re-orientation of the specimen.
