There is much current interest in understanding the dynamics of small bio-logical organisms such as bacteria and spermatozoa, as well as nano-particles and nano-robots in nanotechnology, operating in the low-Reynolds-number regime in confined geometries (for example, near no-slip walls and free surfaces). The sheer variety of both biological micro-organisms and man-made nano-particles together with the geometrical complexities of the environments in which they exist presents significant modelling challenges and there is a need to identify basic paradigms. This talk will offer some simple modelling ideas that give some useful insights into confined low- Reynolds-number swimmer/particle dynamics.
