Silver nanoparticles (AgNPs) is one of the most widely used NPs in the fields of consumer products, catalysis, optoelectronics, chemical sensing, biological imaging, antimicrobial therapy, gene silencing and drug delivery.There are numerous methods for the synthesis of silver nanoparticles (AgNPs) including physical and chemical methods, electrochemical reduction, photochemical reduction and thermal evaporation. Recently, synthesis method using plant extract has developed enormous interest in AgNPs synthesis due to green chemistry approach. Moreover, it is simple, cost effective, eco-friendly, easily scaled up for large scale synthesis, without using toxic and redundant chemicals in solid, liquid and gaseous form. In this study Fig leaves hydro and hydroalcholic (30% alcohol) extract was used for synthesis of AgNPs. The synthesis of AgNPs was monitored at regular intervals by a spectrophotometer. Ag NPs had a peak absorption in the range of 400 to 450 nm. Results showed that the extract with water appears to be weak and lacks the ability to regenerate Ag ions, while the hydroalcoholic extract is very strong and capable of forming nanoparticles.
