A novel preparation of silver nanoparticles using Morus nigra leaves extract, as opposed to the physical and chemical methods had been used in this work. Their active phytochemical compounds will reduce Ag+ and form AgNPs (Ag0). A peak spectrum at 460 nm was formed and confirmed as the Surface Plasmon Resonance (SPR). Vibration at 1643 cm-1 and 3286 cm-1 which characteristic of C=C bonds and (-OH) hydroxyl groups, respectively.
