Kinetics of Biosynthesis of Silver Nanoparticles Using Fusarium Oxysporum

Current Trends in Technology and Sciences (CTTS)
The emergence of nanobiotechnology has
exposed the greener methods of preparation and
application. Many theoretical and experimental works
have been conducted in the biosynthesis of various
nanomaterials and nanocomposites. Biologically
synthesised nanomaterials are exhibiting excellent,
unique and optimised properties. Micro organisms
play an important role in the detoxification of metals
through the reduction of metal ions. This process can
be exploited for biosynthesis of NPs. Experiments
were conducted by varying the concentrations of
silver ions for analysing the formation of silver
nanoparticles by Fusarium Oxysporum. The analysis
has been done for extracellular and intracellular in
the growing cell and whole cell sysytems. Silver
nanoparticles formed by Fusarium Oxysporum was
found to be purely extracellular. In this paper, from
the experimental analysis, an attempt is being made to
suggest a mechanism and elucidate the kinetics for the
formation of silver nanoparticles.
