On the Digestive Ripening Mechanism

Abstract

The literature describes a relatively new method of regulating the size distribution function of nanoparticles, namely, the process of digestive ripening, which, unlike the Ostwald ripening, implies the dissolution of large nanoparticles and the formation of small ones. However, there is still no reasonable explanation of this phenomenon. 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.
