F.irzhak@icp.ac.ruIrzhakV. I.irzhak@icp.ac.ruInstitute of Problem of Chemical Physics of the Russian Academy of Science2006201948655545572706201927062019Copyright © 2019, Russian academy of sciences2019<p>The literature describes a relatively new method of regulating the size distribution function of nanoparticles - the process of digestive ripening, which, unlike Ostwald ripening, consists in dissolving large nanoparticles and forming small ones. However, a reasonable explanation of this phenomenon is still missing. The work substantiates the mechanism of the process, based on taking into account the dependence of the critical radius of the nanoparticle on the concentration of monomeric units and the size of the ligand layer.</p>Ostwald ripeningdigestive ripeningnanoparticlesligand layerоствальдовское созреваниедигестивное созреваниенаночастицылигандный слой[Лифшиц И.
