This research work deals with green synthesis and characterization of silver nano particles. The authors have developed five different green synthesis methods to develop silver nanoparticles. The five methods are: Electrolytic deposition of silver nanoparticles based on principles of green chemistry, Tollens method using green technology, Green Synthesis of Silver Nanoparticles by electrolytic Deposition of X-Ray Film, Green Synthesis of silver nanoparticles using X-Ray films and Green deposition of silver nanoparticles on iron nails using electronegative property.
