Small scale catalytic swimming devices have the potential to enable futuristic applications such as targeted drug delivery and repair within the body. One of the key challenges to move towards these applications is to achieve control over their trajectories. I will describe how the rotational behavior for swimming devices can be modified and controlled to achieve this goal. In addition I will discuss the scaling of transport properties with device size, and the potential to exploit these variations to allow autonomous navigation in analogy to the "run and tumbling" strategy used by bacteria.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
