ABSTRACT For many years, nanotechnology has been one of the fastest growing technologies in the world. This field involves many interesting issues, and one of them are metal nanoparticles. As the interest in bimetallic nanoparticles is growing, it is becoming necessary to find new ways to synthesize them. One of such new methods is biological synthesis, which can be applied in various scientific contexts and, for this reason, has attracted much attention over the last few years. This work describes a biological method for the synthesis of Au/ZnO/Ag trimetallic nanoparticles using Meliloti officinalis extract. The obtained Au/ZnO/Ag trimetallic nanoparticles were characterized by UV-Vis, Scanning electron microscopy （SEM）, Fourier transform infrared spectroscopy （FTIR）, Transmission electron microscopy （TEM） and Atomic Force Microscopy （AFM）. Those techniques confirmed the effectiveness of the biological method for synthesizing Au/ZnO/Ag trimetallic nanoparticles because the obtained nanoparticles were about 20?nm in size.
