Mechanobiology is an exciting field gaining more and more interest. Hence, we know today that cells probe their environment making use of mechanical forces which are ultimately responsible for important processes such as differentiation of stem cells, initiation of transcriptional programs, driving of morphogenesis, migration of cells and control of malignancy. The tools to measure or trigger these forces are currently based on highly specialized and low-throughput methods that are mostly used in laboratory settings. High spatiotemporal sensing and actuating of in vitro and in vivo cells would enable a myriad of applications in basic cell biology, stem cell therapy, neuroscience and cancer diagnosis. Here, we propose the development of a novel sensor/actuator platform for bi-directional cell-level interaction based on acoustic waves .
Phononics, emerging modality extending acoustics like photonics extends optics, describes the integrated manipulation of high frequency acoustic waves. It allows nowadays driving and sensing MHz- to GHz-level ultrasound waves translating in shaped acoustic fields with sub-mm to sub-micron resolution. These waves can interact through acoustic windows with biologic material in the bulk of a sample, at interfaces within target systems or on surfaces where target systems can be located. Further, the transducers and waveguides required to launch, receive and steer phononic waves are currently being integrated with their support (CMOS) electronics to produce agile interaction platforms for cell analysis and interface.
