Confirmation of biosynthesized silver nanoparticles (AgNPs). (A) Color changes in the Phyllanthus emblica fruit extract (PFE) after addition of silver nitrate (1 mM aqueous solution of AgNO3) for nanoparticles synthesis; (B) UV–visible spectrum of AgNPs synthesized by phytochemical agents in the PFE. The peak at 430 nm corresponds to the surface plasmon resonance of AgNPs.
