Green Synthesis, Characterization, and Investigation Antibacterial Activity of Silver Nanoparticles Using Pistacia atlantica Leaf Extract

Abstract

The present article reports on a simple, economical, and green preparative strategy for synthesis silver nanoparticle with Pistacia atlantica leaf extract as a reductant, stabilizer, and capping agent. The green AgNPs were characterized by ultraviolet-visible (UV-Vis) spectrometer, energy dispersive X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDX), and Fourier transform infrared (FTIR) spectrophotometer. The XRD pattern provided evidence for the formation of face-centered cubic structure with an average size of 17–18 nm. UV-Vis and FTIR were used to identify the biomolecules and capping reagents in the Pistacia atlantica leaf extract that may be responsible for the reduction of silver ions and the stability of the bioreduced nanoparticles. This work proved the capability of using biomaterial towards the synthesis of silver nanoparticle, by adopting the principles of green chemistry. In addition, the antibacterial activity of biologically synthesized nanoparticles was proved against gram-positive (Streptococcus pyogenes and Staphylococcus aureus) and gram-negative (Salmonella paratyphi B, Klebsiella pneumonia, Escherichia coli, and Pseudomonas aeruginosa) bacteria.
