Biogenic Synthesis of Silver Nanoparticles Using Azadirachta Indica and Acorus Calamus Extract and Evaluation of Anti Bacterial Activity

Abstract

In recent science Nanotechnology is a burning field for researchers. Nanotechnology deals with the Nanoparticles having a size of 1-100 nm in one dimension used significantly concerning medical chemistry, atomic physics, and all other known fields. Nanoparticles are used immensely due to their small size, orientation, physical properties, which are reportedly shown to change the performance of any other material which is in contact with these tiny particles. These particles can be prepared easily by different chemical, physical, and biological approaches. But the biological approach is the most emerging approach of preparation, because this method is easier than the other methods, ecofriendly and less time-consuming. The Green synthesis was done by using the aqueous solution of Azadirachta indica leaf extract and AgNO3. Silver was of particular interest for this process due to its evocative physical and chemical properties. A fixed ratio of plant extract to metal ion was prepared and the color change was observed which proved the formation of nanoparticles. The nanoparticles were characterized by UV-vis Spectrophotometer, FTIR, DLS, Zeta Analysis, XRD, and SEM. The nanoparticles were found to have the size ranges from 160-180 nm.
