Abstract

A significant decrease in the diffusivity of phospholipid molecules at an aqueous-oil monolayer was observed experimentally when the bathing solutions had different viscosities η1 η2. Near the point of isoviscosity η1 η2, the diffusion constant at the monolayer can be drastically affected by a slight change in the viscosity mismatch. We interpreted this phenomenon by considering the effect of vertical fluctuations which affect the long-term dynamics of two-dimensional lateral diffusion at the monolayer.
