Research Project

When we dive headlong into the water, we drift for a while before the viscous water brings us to a halt. A bacterium in contrast, would come to an immediate halt within microseconds. Swimming strategies at these low Reynolds numbers must therefore be quite different from what we are used to. Nature has devised cunning swimming strategies with screw-like or beating motion of flagella. Inspired by these effective propulsion mechanisms, I study how these could be adapted and used in artificially designed swimmers. Micro-fabrication has already succeeded to build ever smaller swimmers? however only in small numbers. Using the self-assembly potential of DNA origami it will be possible to fabricate artificial swimmers in large numbers.

Beyond the mere mechanism of propulsion, the interaction of swimmers is a controversial topic. It is not completely understood how different swimmers sense each other. That they do interact is however undisputed, as synchronization of cilia and swimmers such as sperm is widely observed. Having advanced simulation techniques and computational resources available, I can address these questions from a numerical point of view.
