Structural formation and many-body effect of concentrated dendrimer solutions by computer simulations

Abstract

Coarse-grained molecular dynamics simulations have been performed in order to study charged dendrimers in an aqueous solution. The structure factor, counterion distribution and effective interaction between molecules are clarified numerically. In particular, the many-body interactions in a triplet system are investigated, which is of importance in concentrated systems. These results shed new light on the analysis of recent small-angle X-ray and neutron scattering experiments on dendrimer solutions. © International Union of Crystallography 2007.
