Abstract

Aqueous suspensions of nanocomposite microcapsules containing gold (5, 10, and 20 nm) and magnetite nanoparticles in the structure of polyelectrolyte shells are prepared by the polyionic assembly procedure. The shells of microcapsules with different numbers of layers and different structures were analyzed using transmission electron, atomic force, and confocal microscopy. The thickness and roughness of microcapsule shells and the dependence of these parameters on the number of adsorption cycles for nanoparticles are studied. It is found that the uniformity of the distribution of colloidal gold nanoparticles in the nanocomposite shell containing magnetite nanoparticles depends on their size.
