The biosynthesis of silver nanoparticles was successfully achieved using Pistacia lentiscus leaves extract and silver nitrate. The plant extract was mixed with silver nitrate, incubated at 50°C and synthesis of nanoparticles was followed using UV–Vis spectroscopy. The reaction was completed in three hours and the resultant nanoparticles were characterized using XRD and TEM techniques. The average size of the produced nanoparticles was found to 24-26 nm. The antifungal and antibacterial activities of the biosynthesized silver nanoparticles were investigated using disc diffusion method. The results showed that these nanoparticles displayed antimicrobial a good activity against fungal as well as bacterial cultures.
