Abstract
In recent years, science and industry have increasingly focused on nanotechnology, particularly the synthesis of nanoparticles. Although various synthesis methods are available, many are inefficient in terms of material and energy consumption. Green chemistry offers an alternative, emphasizing the use of plant-based materials as a reliable, straightforward, non-toxic, and eco-friendly approach that bridges nanotechnology and biotechnology. The present study investigated a novel method for synthesizing silver nanoparticles (AgNPs) using leaf and flower extracts of feverfew (Tanacetum parthenium L.). When the extract was exposed to aqueous silver ions, reduction occurred, resulting in the green synthesis of AgNPs. Ultraviolet–visible spectroscopy (UV–vis) showed a characteristic absorbance peak at 400 nm, confirming nanoparticle formation. The zeta potential of the AgNPs ranged from –30 to –90 mV, indicating good stability. Dynamic light scattering (DLS) revealed an average particle size of 68.6 nm, while field emission scanning electron microscopy (FESEM) images indicated an average size of 65.7 nm. Energy-dispersive X-ray analysis (EDX) confirmed the presence of elemental silver, validating nanoparticle synthesis. X-ray diffraction (XRD) analysis further supported these findings, showing an average particle size of 67.7 nm. Fouriertransform infrared (FTIR) spectroscopy identified peaks at 3436, 2929, 1604, 1383, and 1029 cm–1, corresponding to functional groups involved in nanoparticle stabilization. In conclusion, these findings demonstrated that the nanophytosynthesis of AgNPs using T. parthenium extracts is a rapid, efficient, eco-friendly, and simple alternative to conventional synthetic methods.
