Digestive ripening yields atomically precise Au nanomolecules

Atomically precise Au nanomolecules yielded through digestive ripening establishes that regardless of the pathway, both DR and Brust methods lead to the formation of atomic precise Au NMs.

On the mechanism of the process of digestive ripening

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.
