New method to prepare silver nanoparticles (Ag-NPs) from reduces aqueous solutions of silver nitrate and a mixture of (i) Zinc (ii) Copper as reducing agents and guar gum as a stabilizer. At different temperature and pH=8. UV-Vis spectroscopy, zeta potential analysis, X-Ray diffraction (XRD), and scanning electron microscope (SEM) describe the structure and stability of Ag-NPs. According to SEM result, the particles have spherical shape with particle size 50±30 nm. The UV-Vis spectra of the result solution of Ag-NPs show an absorption peak at 429 nm and 440 nm for Zinc and Copper respectively. Nano silver showed stability for long periods of time to more than nine months.
