A Nanocapsule Based on Natural Mineral Clinoptilolite Surrounded by a Lecithin Envelope

A technology for obtaining nanoparticles of natural clinoptilolite, a mineral from the zeolite family, under laboratory conditions has been developed. The size of zeolite particles was determined by scanning electron microscopy, and the size of nanocapsules was determined by dynamic light scattering. A method for applying a layer of alcohol-soluble phosphatidylcholine (lecithin) onto the surface of a nanoparticle has been proposed. The adsorption of lecithin by clinoptilolite particles was studied by ultraviolet spectrophotometry. It has been shown that the formation of the complex of phospholipid and zeolite in ethyl alcohol had a two-phase kinetics: in the initial phase, the adsorption of lecithin was recorded; it then desorbed into the solvent.
