Query: Interplay between hydrodynamics and the free energy surface in the
  assembly of nanoscale hydrophobes   Solvent plays an important role in the relative motion of nanoscopic bodies,
and the study of such phenomena can help elucidate the mechanism of hydrophobic
assembly, as well as the influence of solvent-mediated effects on in vivo
motion in crowded cellular environments. Here we study important aspects of
this problem within the framework of Brownian dynamics. We compute the free
energy surface that the Brownian particles experience and their hydrodynamic
interactions from molecular dynamics simulations in explicit solvent. We find
that molecular scale effects dominate at short distances, thus giving rise to
deviations from the predictions of continuum hydrodynamic theory. Drying
phenomena, solvent layering, and fluctuations engender distinct signatures of
the molecular scale. The rate of assembly in the diffusion-controlled limit is
found to decrease from molecular scale hydrodynamic interactions, in opposition
to the free energy driving force for hydrophobic assembly, and act to reinforce
the influence of the free energy surface on the association of more hydrophilic
bodies.
