Abstract
The aim of this work was to develop the method of preparation of magnetically responsive, loaded nanocapsules based on a liquid core encapsulation by polyelectrolyte (PE) multilayer adsorption. Magnetically responsive drug nanodelivery systems were prepared by the sequential adsorption of PEs (layer-by-layer technique) using biocompatible PEs (poly-l-lysine as the polycation and poly-glutamic acid as the polyanion). The model lipophilic drug, β-carotene, was successfully encapsulated in the liquid core while Fe3O4 nanoparticles were embedded into the PE multilayer shell. This magnetically responsive drug nanodelivery system may be a promising platform for future targeted therapies (e.g. cancer) or other biomedical applications (e.g. separation systems and diagnostics).
