  We present a thermodynamically consistent mesoscopic model of protein
adsorption at liquid-solid interfaces. First describing the equilibrium state
under varying protein concentration of the solution and binding conditions, we
predict a non-trivial (non- monotonic) dependence of the experimentally
observable properties of the adsorbed layer (such as the surface density and
surface coverage) on these parameters. We subsequently proceed to develop a
dynamical model consistent with the equilibrium description, which
qualitatively reproduces known experimental phenomena and offers a promising
way of studying the exchange of the adsorbed proteins by the proteins of the
solution.
