Abstract

Silver nanoparticles (AgNPs) have unique physicochemical characteristics that render them very appropriate for various biomedical applications. AgNPs were synthesized in a study by an environmentally friendly and cost-effective method where an aqueous extract of Artemisia lerchiana was used as a bioreducing and stabilizing agent. To characterize the synthesized nanoparticles, a conjunction of analytical methods was employed, such as UV–Visible spectrophotometry, Fourier Transform Infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and atomic force microscopy (AFM). The UV–Vis spectrum indicated the formation of nanoparticles with a typical surface plasmon resonance peak situated at 480 nm. TEM examination showed mostly spherical-shaped nanoparticles with a size of 4–19 nm. FTIR spectra showed the presence of functional biomolecules that reduced silver ions and gave AgNPs stability. This green synthesis method highlights the possibility of using plant-based nanoparticle synthesis in biomedical, environmental, and industrial fields.
