Biosynthesis of gold nanoparticles has
emerged as an important area in nanotechnology and biotechnology due to growing
need to develop environmentally benign technologies. Generally, nanoparticles
are prepared by a variety of chemical methods which are not environmentally
friendly. In the present study, we report a rapid and convenient method to
reductively prepare gold nanoparticles from auric chloride using aqueous
extract of Mirabilis jalapa
flowers. The flower extract acts as a reducing agent and encapsulating cage for
the gold nanoparticles. The production of gold nanoparticles has been done by
the controlled reduction of the Au3+ ion to Au0. The
formation of gold nanoparticles has been established by FT-IR and UV-Vis
spectroscopy, as well as by TEM, XRD, EDAX and AFM. The study suggests that M.
jalapa
flowers can be a cheap source as a reductant for the production of gold
nanoparticles.
