Abstract: The invention concerns a method for producing nanocapsules and microcapsules comprising a polyelectrolyte shell by surface precipitation from the solution, by applying a shell to template particles comprising the steps (a) providing a dispersion of template particles of suitable size in a salt-containing liquid phase which contains the components required to form the shell in a dissolved form and (b) precipitating the components from the liquid phase onto the template particles under conditions which enable the formation of a shell around the template particles that has a thickness of from 1 to 100 nm.
