Abstract
In this work, we present a simple green method for Ag and Au nanoparticles (NPs) synthesis in an aqueous medium. Ag and Au NPs were synthesized by chemical reduction method, using amino acid L-Methionine as reducing as well as a stabilizing agent. The size of Ag and Au NPs was controlled by changing the pH values of the reaction mixture. They were characterized by UV-Vis spectroscopy, FTIR spectroscopy, and measurement of electrophoretic properties. The size of NPs was determined by atomic force microscopy (AFM) and dynamic light scattering (DLS) measurement.
