Abstract

ABSTRACT A green, low-cost, and reproducible Cycas leaf–negotiated synthesis of silver nanoparticles is reported. X-ray and transmission electron microscopy (TEM) analyses are performed to ascertain the formation of Ag nanoparticles. Nanoparticles almost spherical in shape having the size of 2–6 nm are found. Rietveld analysis to the X-ray data indicated that Ag nanoparticles have fcc unit cell structure. Ultraviolet (UV)-visible study revealed the surface plasmon resonance at 449 nm. An effort has been made to understand the possible involved mechanism for the biosynthesis of Ag nanoparticles. Present procedure offers the benefit of eco-friendliness and amenability for large-scale production through scaling up.
