Extensive work has been done to explore the potential promises of plant systems in the synthesis of metal nanoparticles. Herein, a convenient and rapid process for the formation of silver nanoparticles with natural reducing and capping agents of Daucus carrota (L.) is reported. The synchronization of secondary metabolites and enzymes as reducing/capping agents plays a vital role in the synthesis and stability of silver nanoparticles for approximately two months. Stable silver nanoparticles were formed by reacting tap root extract of D. carrota with an aqueous solution of AgNO3, which reduced Ag++ to Ag0. The synthesized silver nanoparticles were further characterized using UV spectrophotometry, Energy Dispersive X-ray Spectroscopy (EDAX), Scanning Electron Microscopy (SEM), and X-ray Diffraction (XRD) methods. The synthesized silver nanoparticles were spherical and stable in aqueous medium ranges from 31–52 nm.
