The 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 کاملRegions of attraction between like-charged conducting spheres
Two positively charged conducting spheres have been shown to attract at close enough range, unless they have a charge ratio that would result from contact. We give analytical results for the charge ratio at which the cross-over between electrostatic attraction and repulsion occurs, as a function of the sphere separation.

متن کاملCounterion 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 کاملAttraction between Like Charged Surfaces Mediated by Uniformly Charged Spherical Colloids in a Salt Solution
Like-charged macromolecules repel in electrolyte solutions that contain small (i.e. point-like) monovalent coand counterions. Yet, if the mobile ions of one species are spatially extended instead of being point-like, the interaction may turn attractive. This effect can be captured within the mean-field Poisson-Boltzmann framework if the charge distribution within the spatially extended ions is ...
متن کاملAttraction between like - charged colloidal particles induced by a surface : a density - functional analysis
We show that the first non-linear correction to the linearised PoissonBoltzman n (or DLVO) theory of effective pair interactions between chargestabilised, co lloidal particles near a charged wall leads to an attractive component of entro pic origin. The position and depth of the potential compare favourably with rec ent experimental measurements 82.70.Dd;64.10th;83.20Di Typeset using REVTEX 1 R...
