In this study, silver nanoparticles (AgNPs) were synthesized using methanol extract of Semenovia. suffruticosa. The prepared AgNPs (SS-AgNPs) were examined by ultraviolet-visible spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-raydiffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscope (SEM). Afterward, biological activities including cytotoxicity, ability to generate reactive oxygen species (ROS), antileishmanial and antibacterial effects were investigated. According to the UV-Vis spectroscopy, absorption peak at 430 nm indicates the synthesis of AgNPs. TEM and SEM image of AgNPs shows spherical shape with size range of 20–70 nm. FTIR analysis displayed the involvement of phytochemical constituents in synthesized nanoparticles. The X-ray diffraction analysis confirmed the synthesis of highly pure AgNPs with high crystallinity and Cubic shape with …
