Green Synthesis and Characterization of Silver Nanoparticles using Feverfew (Tanacetum parthenium L.) Leaf and Flower Extracts

In recent years, science and industry have concentrated on nanotechnology such as nanoparticles synthesis. Various synthesis methods exist, but many are inefficient in terms of material and energy usage. The green chemistry approach emphasizes the use of plant materials as a dependable, straightforward, non-toxic, and eco-friendly method that links Nanotechnology and Biotechnology. The current study focused on a novel approach for producing silver nanoparticles (AgNPs) by utilizing Feverfew (Tanacetum parthenium L.) leaf and flower extract. Exposure of this extract to aqueous silver ions led to their reduction and the green synthesis of silver nanoparticles. Ultraviolet spectroscopy (UV-vis) indicates that AgNPs exhibited peak absorbance at ۴۰۰ nm. Zeta potential of AgNPs ranged from -۳۰ to -۹۰ mV. In dynamic light scattering (DLS) the average particle size was ۶۸.۶ nm. Field emission scanning electron microscopy (FESEM) image of AgNPs displayed an average size of ۶۵.۷ nm. Energy dispersive X-ray analysis (EDX) validated silver element presence, verifying the existence of AgNPs. X-ray diffraction (XRD) revealed an average particle size of ۶۷.۷ nm. Fourier transform infrared (FTIR) spectroscopy confirmed the presence of peaks at ۳۴۳۶ cm-۱, ۲۹۲۹ cm-۱, ۱۶۰۴ cm-۱, ۱۳۸۳ cm-۱, and ۱۰۲۹ cm-۱ which suggest the presence of functional groups associated with the AgNPs. In conclusion, the findings indicate that nanophytosynthesis of AgNPs with T. parthenium leaves is a rapid, helpful, eco-friendly, effective and simple alternative to traditional synthetic methods.
