The interfacial dynamics of polymers and water is theoretically
examined. The coupling between thermal fluctuations and the
hydrodynamics at a liquid/solid boundary leads to a repulsion of
polymers from the interface. Starting from a Fokker-Planck equation,
we give scaling relations for this repulsion which are confirmed by
computer simulations. The dynamics of end grafted DNA molecules in
electric fields is studied and possible applications for biosensing purposes are
discussed. In atomistic simulations, the dynamics and structure of
water at hydrophilic and hydrophobic substrates and the hydrodynamic
boundary condition at these surfaces is analyzed.
