Abstract

Alternate adsorption of the molecules of poly(allylamine hydrochloride) (PAA) and sulfated β-cyclodextrin (sulfo-β-CD) is studied by piezoelectric microweighing upon the formation of coatings of nanosized thicknesses by the polyionic assembly procedure. The thickness of planar coatings on the surface of single-crystalline silicon is determined by ellipsometry. The layer-by-layer character of the formation of planar nanosized coating is revealed and assumptions about the structure of the PAA and sulfo-β-CD bilayers are stated. A comparison of the spherical microparticles of polystyrene, as well as manganese and calcium carbonates, demonstrated that it is feasible to use microparticles of calcium carbonate as a template for producing microcapsules. Microcapsules with shells containing five (PAA/sulfo-β-CD) layers are prepared and studied by confocal fluorescent microscopy.
