    "abstract": "The classical Gibbs-Donnan equilibrium describes excess osmotic pressure\nassociated with confined colloidal charges embedded in an electrolyte solution.\nIn this work, we extend this approach to describe the influence of multivalent\nion binding on the equilibrium force acting on a charged rod translocating\nbetween two compartments, thereby mimicking ionic effects on force balance\nduring in vitro DNA ejection from bacteriophage. The subtle interplay between\nGibbs-Donnan equilibrium and adsorption equilibrium leads to a non-monotonic\nvariation of the ejection force as multivalent salt concentration is increased,\nin qualitative agreement with experimental observations.",
