Estimation of the Aggregate Stability of Silver Nanoparticles in a Gel Composition

The aggregate stability of silver nanoparticles (Ag – NPs) in a gel composition is estimated. It is established that during long-term storage (for 3 years), a decrease in the number of nanoparticles with sizes of 1–5 and 5–10 nm and a significant increase in the number of nanoparticles with sizes of 10–15 nm are observed. At the same time, the fraction of silver nanoparticles with sizes greater than 30 nm is less than 5%.
