Abstract
The invention shows that it is possible to produce a depot matrix for biologically active substances, consisting of carbohydrate microspheres, such that the carbohydrate polymers included in the microsphere are stabilized to a microsphere by crystallization, which implies using non-covalent bonds, the substance enclosed retaining its biological activity.
