Significance The physical properties of proteins and polyions in electrolyte solutions are of crucial importance for understanding biological processes and for controlling biotechnological processes. The concentration of salt controls the range and strength of the interactions in these complex electrolytes. Here, multiscale coarse-grained molecular dynamics simulations reveal long-range interactions between nanoparticles in aqueous solutions at high monovalent salt concentrations. The simulations explain the crystallization of nanoparticles even when they are strongly charged and explain the reentrant attractive to repulsive to attractive interactions as the nanoparticle charge density increases in high monovalent salt-concentration conditions.
