Abstract

BIOGENIC COPPER NANOPARTICLES FROM THE AQUEOUS STEM EXTRACT OF CERIOPS TAGAL

Larkins Ramteke*, B. L. Jadhav and Poonam Gawali

Abstract

Synthesis of cost effective, reliable and eco-friendly nanoparticles is an expanding branch of green nanotechnology. Ceriops tagal, a mangrove plant has wide range of medicinal properties. Synthesis of C.tagal mediated nanoparticles may further enhance its medicinal potency. The aqueous stem extract of C.tagal was used as a bio-reducing agent for synthesis of copper nanoparticles. Reduction of metal ions was confirmed by Ultraviolet-visible absorption spectroscopy, transmission electron microscopy, energy dispersive spectroscopy and X-ray diffraction. Functional groups involved in nanoparticle synthesis were recorded by ATR-FTIR spectra. Nanoparticle formation was dependent on time, temperature and metal salt concentration. UV-Visible spectroscopy demonstrated peak at 500 nm. TEM and XRD results revealed shape and structure of synthesized nanoparticles. These results have indicated formation of metallic copper nanoparticles. This is the first report on rapid biosynthesis of copper nanoparticles synthesized by bio-reduction of copper sulphate solution employing aqueous stem extract of C.tagal.

Keywords: Mangroves, Ceriops tagal, aqueous extract, copper nanoparticles.
