Counterion correlations and attraction between like-charged macromolecules.
A simple model is presented for the appearance of attraction between two like-charged polyions inside a polyelectrolyte solution. The polyions are modeled as rigid cylinders in a continuum dielectric solvent. The strong electrostatic interaction between the polyions and the counterions results in counterion condensation. If the two polyions are sufficiently close to each other their layers of c...
متن کاملThe mean-field theory for attraction between like-charged macromolecules
A mean-field theory based on Gibbs-Bogoliubov inequality is constructed to study the interactions between two like-charged polyions. It is shown that contrary to the previously established paradigm, a properly constructed mean-field theory can quantitatively account for the attractive interactions between two like-charged rods. One of the most fascinating problems that has recently appeared in ...
متن کاملModes of counterion density fluctuations and counterion-mediated attractions between like-charged fluid membranes.
Counterion-mediated attractions between like-charged fluid membranes are long ranged and nonpairwise additive at high temperatures. At low temperatures, however, they are pairwise additive, and decay exponentially with the membrane separation. Using a simple model for the electrostatic attraction between like-charged surfaces, we show that the nature of these attractions is determined by the do...
متن کاملInteraction between charged anisotropic macromolecules: application to rod-like polyelectrolytes.
In this paper we propose a framework allowing one to compute the effective interactions between two anisotropic macromolecules, thereby generalizing the Derjaguin, Landau, Verwey, and Overbeek theory [E. J. W. Verwey and J. T. G. Overbeek, Theory of the Stability of Lyophobic Colloids (Elsevier, Amsterdam, 1948)] to nonspherical finite size colloids. We show in particular that the effective int...
متن کاملEffects of counterion size on the attraction between similarly charged surfaces.
Interaction between similarly charged surfaces can be attractive at high electrostatic coupling constants Ξ = l(B)Z(2)/μ(GC), where l(B) is the Bjerrum length, μ(GC) the Gouy-Chapman length, and Z the valency of counterions. While this effect has been studied previously in detail, as a function of surface charge density and valency of the pointlike counterions, much less is known about the effe...
