Abstract

Rapid synthesis of AgNPs by plant of Acacia concinna fruit extract. Synthesis of Ag Nps has been planned as a valuable and eco-friendly approach. This research work are cost effective as well as eco-friendly i.e reduction method using the fruit extract of acacia concinna plant and aqueous silver nitrate solution, for the preparation of the AgNPs. This plant extract act as both reducing and capping agent. The essential ingredients liable variables are triterpenes, flavonoids and eugenol, are present in the fruit extract that used for the formation of AgNPs. After the reduction process silver (Ag+) ions was monitored, it showed the formation of Ag NPs using UV-visible spectrophotometry, which exhibits the absorption peak around at 430 nm. The sizes of nanoparticles were calculated by transmission electron microscopy (TEM) and X-ray diffraction (XRD). In addition, by using Agar-Well Diffusion Method, the antimicrobial activity of synthesized AgNPs was investigated by against Escherichia coli. For the conversion of Ag+ to AgNPs at room temperature, this method could be proved a better substitute to chemical synthesis method without the contribution of any hazardous to environment.
