Acoustically propelled microparticles: From fundamentals to applications
Artificial microparticles that exhibit active propulsion when exposed to ultrasound have great potential for practical applications in fields such as medicine and materials science. For example, these acoustically propelled microparticles could - resembling remote-controlled micro-submarines - be used for targeted drug delivery or microinvasive surgery. Furthermore, materials based on such particles constitute active materials that can exhibit extraordinary properties not found in conventional materials. In this talk, I will give an overview of our investigation of the fundamental properties of these particles, our first steps toward their potential applications, and our planned future steps to turn these applications into reality. In the second part of the talk, I will give an insight into my other main topics of research.



![3D visualisation of human neuronal tissue reconstructed by multi-scale X-ray phase contrast tomography. Neuronal cell nuclei are shown in yellow for the granule neurons in the dentate gyrus region of the hippocampus. Blood vessels are shown in red. By changing the X-ray optical magnification in the multi-scale recordings, one can zoom into regions-of-interest (red ovals). In these scans the resolution is high enough to resolve sub-structures of the nucleus, associated with different DNA packing regimes.
