Evaluation of Biologically Synthesized Silver Nanoparticles by the Bioreduction Method

The synthesis of metal nanoparticles using biological methods is an expanding research area due to the potential applications in nanomedicines. In the present study silver nanoparticles synthesize rapidly by using the methanol extract of leave of Zosimia absinthifolia. The synthesized silver nanoparticles were observed and characterized by UV-visible spectrophotometry, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy. The TEM study showed the formation of silver nanoparticles in the 5.2–74.4 nm range and average 8.8 nm in size. SEM showed the formation of silver nanoparticles with a mean size of 46.3 nm. The XRD study showed that the particles are crystalline in nature, with a face centered cubic structure. The leaves of Zosimia absinthifolia were found to display strong potential for the synthesis of silver nanoparticles as agents by rapid reduction of silver ions (Ag+ to Ag°). The approach of phytosynthesized silver nanoparticles using Z. absinthifolia appears to be a cost-efficient, eco-friendly, and easy alternative to conventional methods of synthesis.
