Ϊ†Ϊ©ΫŒΨ―Ω‡    Nano-derivatives have gained wide attention, especially nano-silver compounds, due to their wide uses in the medical fields. in this study sider leaves were extracted with 99% absolute ethanol for 24 hours. extracts were reacted with silver nanoparticles in the presence of deionized water by a gel method. as the nano-black product, the resulting compound was characterized, and diagnosed by physical and spectroscopic methods, including infrared spectroscopy, x-ray diffraction, electron microscopy, and atomic force microscopy. the resulted compound, was tested for its biological activity against gram-positive (staphylococcus aureus, e. coli, and pseudomonasaeruginosa) bacteria, compared with neomycin, tetracycline, and antibiotics. the results revealed significant antibacterial effect compared with commercial antibiotics.
