Popis: Silver nanoparticles were synthesized using different aqueous concentrations of silver nitrate (0.5,1, 2, 3) with olive leaf extract as reductive factor. The reaction showed a strong change in color from yellow to dark brown. Antimicrobial activity against pathogenic bacteria like Staph aureus, E. coli was studied. Spectral properties were studied by using UV- visible spectrophotometer, all concentrations shown peaks at (435)nm. The nanosilver particles tested by Dynamic light scattering (DLS) so the size particles were about (80-126)nm, zeta potential values were (-17 - -23)m V. Biological silver nanoparticles gained interest in recent past owing to its simple preparation, low cost, ecofriendly and their products more stability.
