Synthesis and characterization of gold nanoparticles using Ficus religiosa extract
Journal Title: Carbon - Science and Technology - Year 2013, Vol 5, Issue 1
Abstract
We report a cost effective and eco-friendly biosynthesis of gold nanoparticles (F-AuNPs) using aqueous extract of Ficus religiosa as the reducing and stabilizing agent. These nanoparticles were characterized by various techniques such as UV-Vis, XRD, TEM and FTIR. The characteristic surface plasmon peak was observed at 540 nm while XRD analysis suggested it to be a face-centered cubic (fcc) structure with peaks at 38.06, 44.46, 64.75 and 77.56 degrees. FTIR studies indicated the capping of the nanoparticles with polyphenols, amines and carboxylates present in the extract of Ficus religiosa whereas TEM analysis showed spherical morphology with other shapes such as triangles and hexagons. The F-AuNPs were found to be non-toxic to HEK 293 cells, thereby suggesting their potential application in the field of nanobiotechnology.
