ION-ELECTROSTATIC INTERACTION IN SYSTEMS OF INORGANIC NANOPARTICLES AND BIOLOGICAL CELLS IN ELECTROLYTE SOLUTION

摘要

The solution of the Debye-Huckel equation for a system of spheres with arbitrary radii and surface charge in electrolyte solutions is described. The general theoretical approach to describe such systems is elaborated. The practically important case of two spheres is considered in detail. Finite closed formulae to calculate the interaction energy of two spherical particles with constant surface charges are obtained from general expressions in zero approximation. Known relationships follow from our formulae in limiting cases.
