Novel, fast, bio-derivatized sonochemical synthesis of gold nanoparticles by using piper betle leaf broth as a reducing and capping agent

Abstract

The use of biomolecules hosted products for synthesis of nano sized materials of increasing interest to benign medicinal field. We report a biomolecules hosting, rapid, environmentally benign, bio-degradable, non-toxic, and sonochemical synthesis of gold nanoparticles by using piper betle leaf broth as a reducing and capping agent. The aqueous reaction of medium containing gold nanoparticles showed a peak at 540 nm was studied by UV-Vis spectra. In addition, we determined the size of the nanoparticles and optical energy gap from the surface plasmon absorption peak. The crystalline structural characteristics of a biomolecules hosted gold nanoparticles were studied by X-ray diffraction. The morphology of nanoparticles was analyzed by scanning electron microscopy. The stoichiometric chemical composition of elemental presence in the medium was determined by energy dispersive spectrum. The presences of biomolecules which are act as capping agents around the nanoparticles were studied by fourier transform infrared spectroscopy.
