Competence of different methods in the biosynthesis of silver nanoparticles


Nanosilver has become one of the widely used nanomaterial in consumer products. The formation of nanoparticles depends on several factors like the concentration of silver ions, time and method of synthesis. In the present work nanosilver particles were synthesized using four different edible plants by three different methods employing heat and sound waves. Rapid reduction of silver ions to nanosilver was noticed in all methods, sonication method being quicker comparatively. The synthesized silver nanoparticles were characterized by UV-visible spectroscopy, XRD, Debye-Scherrer’s equation and SEM analysis. In sonication method, nanoparticles of size less than 50 nm were obtained. The SEM analysis revealed that the nanoparticles were well dispersed without agglomeration. The successful utilization of sonic waves in the formation of silver nanoparticles is quite apparent from the results.
