Abstract
Polyelectrolyte microcapsules were obtained by the method of sequential deposition of oppositely charged poly(allylamine hydrochloride) and poly(sodium 4- styrenesulfonate) on the surface of colloidal vaterite particles. Modification of capsule shells with the synthesized magnetic iron oxide nanoparticles aims not only to control the localization of capsules, but also to tune their permeability. Application of low frequency nonheating magnetic field for these purposes offer prospects of high penetration ability into tissues, high locality and safety, which makes this method more preferable for using in vivo than magnetic hyperthermia. The article describes the effect of an alternating low-frequency magnetic field of various frequencies on the release of fluorescently labeled dextran from capsule shells. The dependence of the amount of released fluorescently labeled dextran on the frequency of the applied magnetic field has a resonant character
