“Background During the last decade, silver nanoparticles (Ag NPs) Nepicastat cell line attract significant attention due to their unique optical, thermal, and electrical properties as well as their use as antibiotic materials, photocatalysts, and conductive nano-inks [1–7]. The methods to obtain Ag NPs of well-defined morphology, size, orientation,

and complex pattern are the subject of numerous researches. In principle, physical and chemical mafosfamide techniques for nanometer-sized metal particle preparation can be used [7–12]. Such methods as chemical vapor deposition, chemical reduction, photolytic reduction, and radiolytic reduction are among them. Reduction of metal ions into neutral clusters is a commonly used treatment in chemical synthesis. The high reactivity of Ag NPs raises difficulties in developing stable colloidal dispersions, since Ag NPs rapidly undergo agglomeration. Therefore, it is urgent to search the methods allowing the acquisition of nanosystems with high storage stability. Silver colloids stabilized by polymers in various solvents are extensively investigated by considering the linear and star-shaped polymers, polymer brushes, block copolymers, and even dendrimers [13–19]. However, the advantages of branched polymer matrices in comparison with their linear polymer analogs for in situ nanoparticles formation are still not clear.
