I will describe how to use well known methods from
soft matter to study the dynamics of systems motivated biologically. In
particular, I will address the effect of hydrodynamics on the motion of
self-propelled particles (a simplified model for swimming microorganisms),
emphasyzing their similarities and differences with colloidal suspensions. I
will also analyze the role hydrodynamic plays in the dynamics of semiflexible
filaments, both passive and active. An idealized model which captures
inextensibility (a characteristic feature of biofilaments such as actin or
microtubules) will serve to highlight the influence of hydrodynamic
interactions in the motion of these systems.
