“…In the seed-mediated growth, the selection of the reducing agent is of great concern, because strong reducing agents can generate new crystal nuclei in solution, which leads to an undesirable size distribution. Typical reducing agents employed in seed-mediated reduction include sodium borohydride, 19,20 ascorbate ions, 15,16,18 oleyl amine, 21 ethylene glycol, 22,23 glucose, 24 etc. The results also depend on a range of easily controllable parameters, such as reagent concentration, the presence of additives, and the order and rate of addition of reagents.…”
