Abstract
AbstractSummary: The paper describes a perspective approach to significantly decrease permeability of polyelectrolyte multilayered capsules and, therefore, to make them more efficient for encapsulation of small molecule species. The polyelectrolyte shell modification by a dense polymer (polypyrrole) provides the capsule shell with water‐resistant and sufficient barrier properties. However, high brittleness of polypyrrole coatings demands more gentle capsule processing conditions. Magnetite iron oxide nanoparticles were used as a shell constituent to provide the capsules with magnetic properties and, therefore, to propose a mild technological protocol for capsule treating.CLSM image of TRITC filled PPy covered capsules prepared by magnetic sedimentation.magnified imageCLSM image of TRITC filled PPy covered capsules prepared by magnetic sedimentation.
