Green synthesis of metal nanoparticles has become a promising synthetic strategy in nanoscience and nanotechnology in recent years. In this work, silver nanoparticles (Ag-NPs) were synthesized from extract of Prosopis facto at room temperature. Formation of Ag-NPs at 1 mM concentration of AgNO3 gave spherical shape nanoparticles with mean diameter about 10.8 nm. The formation of nanoparticle was confirmed by the surface Plasmon resonance (SPR) band illustrated in UV-vis spectrophotometer. The morphology and size of the Ag-NPs were determined using high magnification transmission electron microscopy (TEM). The crystalline structure of obtained nanoparticles was investigated using the powder X-ray diffraction (PXRD) pattern. In addition, these green synthesized Ag-NPs were found to show higher antibacterial activity against multi drug resistant clinical isolates. (C) 2015 Elsevier B.V. All rights reserved.
