The missing link between the Hydration Force and interfacial water: Evidence from computer simulations

In this article I briefly review Molecular Dynamics Simulations studies relevant to the understanding of the physical origin of the controversial Hydration Force. The focus of the review is in simulations of realistic models of hydrophilic surfaces. The results reviewed here show a molecular perspective on how this repulsive, stabilizing force comes from interfacial water.

► Molecular dynamics simulations show strong polarization of interfacial water.
► Interfacial water determines surface potential in hydrophilic charged or neutral surfaces.
► Hydration force is the electrostatic force arising from this strong polarization.
