Solving the Poisson–Boltzmann equation to obtain interaction energies between confined, like-charged cylinders

چکیده
We numerically solve the nonlinear Poisson–Boltzmann equation for two cylinders confined by two parallel charged plates. The repulsive electrical double layer component of the cylinder pair potential is substantially reduced by confinement between like-charged plates. While the effective cylinder surface charge is increased by the confinement, the effective interaction screening length is reduced, this effect being dominant so that the repulsive confined cylinder–cylinder interaction potential is reduced. © 1998 American Institute of Physics. @S0021-9606~98!50144-4#

Solving the Poisson-Boltzmann Equation for Two Parallel Cylinders
The electrostatic interaction between two parallel charged cylinders of arbitrary diameters a1 and a2 is studiedby solvingnumerically thenonlinearPoisson-Boltzmannequation. A limit of particular interest is that of a charged cylinder interacting with a charged plane (a1 f ∞). The interaction free energy is calculated, as a function of the separation distance between the cylinders, for either fi...

Electrostatic potential as well as the local volume charge density are computed for a macromolecule by solving the Poisson-Boltzmann equation (PBE) using the finite element method (FEM). As a verification, our numerical results for a one dimensional PBE, which corresponds to an infinite-length macromolecule, are compared with the existing analytical solution and good agreement is found. As a ma...

متن کاملGBr6NL: a generalized Born method for accurately reproducing solvation energy of the nonlinear Poisson-Boltzmann equation.
The nonlinear Poisson-Boltzmann (NLPB) equation can provide accurate modeling of electrostatic effects for nucleic acids and highly charged proteins. Generalized Born methods have been developed to mimic the linearized Poisson-Boltzmann (LPB) equation at substantially reduced cost. The computer time for solving the NLPB equation is approximately fivefold longer than for the LPB equation, thus p...
