Pressure-responsive macromolecules that change their conformation in response to variations in the film pressure can be used as model systems for studying the mechanism of the fluid transport on nanometer length scales. The ability to visualize pressure-sensitive macromolecules in motion enables quantitative measurements of the local film pressure and the friction coefficient with the substrate.
