Theory and simulations of macroion complexation

A brief overview is given over recent theoretical and simulation work on complexes of oppositely charged macroions. The emphasis is on linear/cylindrical macroions (flexible, semiflexible polyelectrolytes) and spherical/globular macroions (colloids, micelles, globular proteins). We discuss soluble complexes, dense complex phases, and micelles with cores consisting of dense complex phases, stabilized by neutral hydrophilic chains.
