This work represents new method to prepare highly dispersed silver nanoparticles with high yield from waste materials. A simple green route was used for producing silver nanoparticles by reducing silver salt using natural gum, starch and/or glucose in alkali media. The gum had the ability to reduce silver in better control of the silver particle size and stability. Transmission electron microscopy (TEM), dynamic light scattering (DLS) and UV–vis spectroscopy were employed to characterize the synthesized Ag nanoparticles. The results indicated the successful synthesis of nano silver particles with average particle size of 5–10 nm. The produced silver nanoparticles showed good resistance to stomach synthetic fluid (0.5 M HCl).
