Green Synthesis of Silver Nanoparticles using Plant Leaf Extract of Adiantum peruvianum

摘要

Silver nanoparticles are today one of the most commonly used nanomaterials both in fundamental medical sciencesand clinical practices. Advancement in the biological process of plant mediated synthesis of nanoparticle is evolving into a keyarea of nanotechnology offering an easy extracellular synthesis. The current study deals with the synthesis and characterizationof silver nanoparticles using aqueous extracts of Adiantum peruvianum. The synthesis of nanoparticles was confirmed by changein colour from pale green to reddish brown. Further, a peak was obtained at 466nm.Transmission Electron Microscopy (TEM)analysis confirmed the formation of crystalline spherical SNPs of an average size of 2–35 nm. Compositional analysis usingEnergy Dispersive X-ray Spectroscopic Analysis (EDAX) showed strong characteristic signal for silver. The X-ray Diffraction(XRD) study confirmed the particles as silver, with a face-centred cubic geometry. Fourier Transform Infrared Spectroscopy(FTIR) evaluated the functional groups that might be involved in nanoparticles formation. Synthesis from Adiantum peruvianumseem to the best of our knowledge the use of Adiantum peruvianum for the synthesis of silver nanopaerticles is respected for thefirst time. The antibacterial activity, toxicityandantioxidant activity of these silver nanoparticles are under investigation.
