Allium cepa and garlic Allium sativa plants were used to evaluate their potential synthesis of silver nanoparticles and their antibacterial effect on Streptococcus pneumoniae and Pseudomonas aeruginosa. Transmission electron microscopy (SEM) was used to distinguish the morphology of the nanoparticles attained from plant extracts. Energy dispersive X-ray (EDX) spectrometer established the existence of elemental sign of the silver and homogenous allocation of silver nanoparticles. Diffraction by using X ray (XRD) analysis for the formed AgNPs revealed spherical plus cubical shapes structure with different planes ranged between 111 and 311 planes. The antibacterial action of AgNPs against vaginal pathogens, Streptococcus pneumoniae and Pseudomonas aeruginosa was recognized. Our work showed a rapid, ecosafety and suitable method for the synthesis of AgNPs from Allium cepa and garlic Allium sativa extracts and can be used in biomedical applications.
