Query: Extended surfaces modulate and can catalyze hydrophobic effects   Interfaces are a most common motif in complex systems. To understand how the
presence of interfaces affect hydrophobic phenomena, we use molecular
simulations and theory to study hydration of solutes at interfaces. The solutes
range in size from sub-nanometer to a few nanometers. The interfaces are
self-assembled monolayers with a range of chemistries, from hydrophilic to
hydrophobic. We show that the driving force for assembly in the vicinity of a
hydrophobic surface is weaker than that in bulk water, and decreases with
increasing temperature, in contrast to that in the bulk. We explain these
distinct features in terms of an interplay between interfacial fluctuations and
excluded volume effects---the physics encoded in Lum-Chandler-Weeks theory [J.
Phys. Chem. B 103, 4570--4577 (1999)]. Our results suggest a catalytic role for
hydrophobic interfaces in the unfolding of proteins, for example, in the
interior of chaperonins and in amyloid formation.
