GREEN SYNTHESIS AND CHARACTERIZATION OF SILVER NANOPARTICLES USING COLEUS AROMATICUS LEAF EXTRACT

Abstract

The production and characterization of nanoparticles have garnered significant attention in the field of nanotechnology in recent times. UsingColeus aromaticus in the green synthesis of AgNPs offers many advantages over conventional synthesis methods. Gathering plant material, preparing plant extract, synthesizing silver nanoparticles, optimizing reaction parameters, and characterizing the resultant product. XRD observed intensity peaks at 28.5, 31.8, and 38.6 degrees, corresponding to planes 220, 311, and 240, respectively. FTIR spectrum peaks of 3000.48, 2888.89, 2825.30, 1622.33, 1417.58, 1132.81, 901.99, and 583.04 were observed. The SEM image revealed the component parts to be non-uniform, spherical, agglomerated, and having an average size of 28.5 nm. Silver nanoparticles (AgNPs) are produced from Coleus aromaticus extract by use of the phytochemicals in the plant extract, which function as stabilising and reducing agents. AgNPs are successfully synthesized, and their potential applications are supported by their characterization using a variety of analytical methods.
