The synthesis of silver nanoparticles has attracted much attention because their unique shape-dependent optical, electrical, and chemical properties have potential applications in nanotechnology. Silver nanoparticles are used in photographic reactions, catalysis, and chemical analysis. An attempt has been made to study the formation of the metal nanoparticles by reduction of the aqueous metal ions during exposure to the broth of boiled sunflower leaves may be easily followed by UV–vis spectroscopy. After adding the leaf broth to silver nitrate solution, immediately a yellowish brown color forms indicating that silver nanoparticles have been formed.
