Polyelectrolyte coverings on biological templates

Abstract

Process for the preparation of capsules with a shell of polyelectrolytes, characterized in that on a template (templat) selected from aggregates of biological materials and / or amphiphilic several successive layers of polyelectrolyte molecules oppositely charged are deposited, preparing a dispersion first of the particles of the template in an aqueous solution, then adding to this dispersion a kind of polyelectrolyte load equal or opposite to that of the particle surface of the template loading, then adding after the separation of molecules polyelectrolytes surplus may be present, the species of polyelectrolyte charged oppositely used for the construction of the second layer and then optionally depositing, alternatively, more layers of polyelectrolyte molecules oppositely charged and eventually disintegrates then the template.
