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.

基于天然矿物斜发沸石和卵磷脂包封物的纳米胶囊。

已经开发了在实验室条件下获得天然斜发沸石的纳米颗粒的技术,所述斜发沸石是沸石家族的矿物。通过扫描电子显微镜确定沸石颗粒的尺寸,并且通过动态光散射确定纳米胶囊的尺寸。已经提出了将醇溶性磷脂酰胆碱(卵磷脂)层施加到纳米粒子的表面上的方法。通过紫外分光光度法研究了斜发沸石颗粒对卵磷脂的吸附作用。已经表明,在乙醇中磷脂和沸石的络合物的形成具有两个阶段的动力学:在初始阶段,记录了卵磷脂的吸附;在初始阶段,卵磷脂的吸附被记录。然后将其解吸到溶剂中。
