摘要：
The invention relates to a method for producing nano or microcapsules comprising a polyelectrolyte casing, by surface precipitation from the solution, by applying a casing to the template particles. The inventive method comprises the following steps: (a) providing a dispersion of template particles having a suitable size in a saline liquid phase that contains the components required for producing the casing dissolved therein, and (b) precipitating the components from the liquid phase onto the template particles under conditions enabling the production of a casing around the template particles that has a thickness of from 1 to 100 nm.
