Green nanoparticle (NP) synthesis is a novel area of nanotechnology that succeeds in terms of biocompatibility, scalability, cost-effectiveness, and environmental friendliness. Due to the widespread of metal nanoparticles in industrial scale applications, green and efficient process that are required free toxic solvent is being emphasized. Plants have lately been used to produce metal nanoparticles as an alternative approach that apply extracts made from as reducing and capping agent. Due to their excellent properties, silver nanoparticles have been widely used for several applications, including as antibacterial agents, in industrial, household, and healthcarerelated products, in consumer products, medical device coatings, optical sensors, and cosmetics. Regarding this, the purpose of our research firstly was to find out whether the green martials Turkish coffee (TC) and Virginia Creeper (VC) extracted and used for synthesis of silver nanoparticles (Ag NPs) could be recycled for further NP synthesis. Another objective was to compare Ag NPs morphology synthesized by biological reagent to chemical reagents as sodium borohydride (NaBH4) as reductant, and sodium citrate and Polyvinyl-Pyrrolidone (PVP) 55k as the stabilizing agents by conventional method. The characteristics of the Ag NPs was confirmed by transmission electron microscopy (TEM), U.V spectroscopy and dynamic light scattering (DLS) measurements.
