Abstract

Abstract: In this work, simple, economic, eco-friendly modified method with high efficiency was applied for synthesis of silver nanoparticles (Ag NPs) by using polyethylene glycol (PEG) as a capping agent, reductant, and media agent. In order to preparation uniform and small Ag NPs, the reaction parameters such as type of polymer, AgNO3 /Polymer weight concentration ratio, and AgNO3 /NaBH4 molar concentration ratio were modified. The best condition was optimized in concentration ratio of AgNO3 : PEG: NaBH4 where are 1:10:0.01, respectively with 82% efficiency and 98.95% purity. Therefore, this modified polyol method can also be scaled up for synthesis of Ag NPs appropriately. Due to polymeric coating on the Ag NPs, they can be employed as a promising candidate for drug delivery systems. Highlights: Eco-friendly modified polyol method for synthesis of silver nanoparticles was applied. The different parameters in the fabrication of Ag NPs were modified. In this study, Ag NPs with 82% efficiency and 98.95% purity were synthesized. Increasing polymer concentration decreased the particle size of Ag NPs. Applying NaBH4 was decreased the particle size and increased the efficiency of AG NPs.
