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 400 nm. Zeta potential of AgNPs ranged from -30 to -90 mV. In dynamic light scattering (DLS) the average particle size was 68.6 nm. Field emission scanning electron microscopy (FESEM) image of AgNPs displayed an average size of 65.7 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 67.7 nm. Fourier transform infrared (FTIR) spectroscopy confirmed the presence of peaks at 3436 cm-1, 2929 cm-1, 1604 cm-1, 1383 cm-1, and 1029 cm-1 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.
