The ratio of the lateral correlation length and particle radius determines the density profile of spherical molecules near a fluctuating membrane.

Interactions between membranes and molecules are important for many biological processes, e.g., transport of molecules across cell membranes.

Hydrodynamic correlations in three-particle colloidal systems in harmonic traps.

We report on the hydrodynamic correlations between colloids immersed in a low Reynolds number fluid. We consider colloidal arrays composed of three particles; each colloid is trapped in a single harmonic potential and interacts with the other colloids only via hydrodynamic forces. We focus on the role of a third body in the two-body correlation functions.
