Fig. 1From: Silver ion bioreduction in nanoparticles using Artemisia annua L. extract: characterization and application as antibacterial agentsPattern of green synthesis. The chemical reaction of NPs synthesis includes several steps. Polyphenols convert positive Ag+ into the zero Ag0 valent metal, and in the last step of green synthesis the polyphenols coat metal NPs and affect the morphology and size of NPsBack to article page
