Recent interest in the development of new and novel strategies for the
generation of gold nanoparticles stems from their potential applications in
diversified fields.Biosynthesis of nanoparticles is now established as an
emerging area of nanoscience research. A bottom-up ?green? and rapid synthetic
route using Colchicum autumnale leaf broth as reducing and stabilizing agent
produced gold nanoparticles at ambient conditions. The nanoparticles were
characterized by UV?vis spectrophotometer, FTIR, Field Emission Scanning
Electron Microscope, X-ray diffraction and DLS. FTIR spectra indicates that the
reduction of Au3+ to Au0 was mediated by alkaloids present in the plant leaf
broth. The size of synthesized nanoparticles are in the range of 70-120nm,
which has been confirmed by DLS and FE-SEM.The size of nanoparticles decreases
with increase in broth concentration. The morphology was irregular spherical to
polygonal and crystallized in face centered cubic symmetry. - See more at:
