Reaction temperature and concentration of GBE have been successfully optimized to maximize the yield of nanoparticles.

Notes: Temperature-dependent evolution of UV–vis spectra of synthesized nanoparticles at a constant amount of GBE (3%, v/v) and 1 mM of gold and silver salts: (A) GBAuNPs and (B) GBAgNPs. Concentration-dependent evolution of UV–vis at 80°C of (C) GBAuNPs (D) GBAgNPs. Time-dependent evolution of UV–vis at 80°C, GBE 5% concentration of GBE and the respective photograph which shows the color change pattern during nanoparticle synthesis of (E) GBAuNPs and (F) GBAgNPs.

Abbreviations: GBAgNPs, silver nanoparticles from ginseng berry; GBAuNPs, gold nanoparticles from ginseng berry; GBE, ginseng berry extract; OD, optical density; UV, ultraviolet; vis, visible.
