Abstract: The invention relates to a gradual coating method (LBL-technology®) with poloyelectrolytes of microparticles and nanoparticles in aqueous gels and gelatinous media, whereby regularly occurring flocculation and coagulation problems,which arise as a result of high collision frequency (Brownian movement and/or hydrodynamic collision) amongst the particles to be coated and as a result of heterocoagulation with the coating material, can be avoided. The coating compositions are conveyed to the particles which are to be coated by diffusion or by means of external forces of an electric, magnetic, dielectrophoretic and hydrodynamic variety. According to the invention, the coated cores can be disintegrated or dispersed after coating while maintaining the integrity of the multi-layered shell. The coating products and/or the empty coating shells can be obtained once the gel has been broken and can be further processed.
