Contents
In this topic the concept of self-propulsion in biological systems is discussed. In particular the consequences of living in an incompressible/viscous medium on the micron length scale. The concept of irreversibility will be introduced via Purcell's famous scallop theorem. The various mechanisms by which micro-organisms achieve motion are considered in connection to irreversibility. In relation to their strategies to achieve self-propulsion, the far-field hydrodynamic signature of these objects is discussed and the consequences these hydrodynamic modes have for their interaction with walls and other particles.
