LOW COST AND RAPID BIOSYNTHESIS OF SILVER NANOPARTICLES USING CASSIA TORA LEAF EXTRACT
Journal Title: International Journal of Pharmaceutical Sciences and Research (IJPSR) - Year 2019, Vol 10, Issue 10
Abstract
Chemical, physical, and biological methods have been developed to synthesis nanoparticles but chemical and physical methods are involved in the production of toxic by-products which are hazardous moreover the methods are very expensive. To synthesis stable metal nanoparticles with controlled size and shape, there have been searched for inexpensive, safe, and reliable and “green” approach. The present study reports an environmentally friendly, low cost, novel and rapid method for synthesis of silver nanoparticles. We have developed a green synthetic method for silver nanoparticles using Cassia tora leaf extract which acts as a reducing & capping agent. It was observed that use of Cassia tora leaf extract makes rapid and convenient method for synthesis of silver nanoparticles and can reduce silver ions into silver nanoparticles within few seconds of reaction time. UV-Vis spectrometer uses to monitor the reduction of Ag ions and formation of AgNPs in medium. The morphological studies of the biosynthesized nanoparticles are done using UV-Vis, HRTEM & FESEM techniques FTIR was performed to identify the functional groups of carbonyl, hydroxyl, amine and protein molecule which form a layer covering AgNPs and stabilize the AgNPs in medium.
