Abstract
A novel method of protein encapsulation is proposed. Preformed protein aggr egates are covered with polyelectrolyte layers by means of layer-by-layer a dsorption. The polyelectrolyte membrane prevents protein leakage out of the capsule. Using chymotrypsin as a model enzyme the capsule wall selective p ermeability was demonstrated for substrates and inhibitors of different mol ecular weight and solubility.
