Abstract :
Growth and development of biologically
synthesized metal nano particles have attracted
significant attention in field of nanotechnology due to
their potential use for human benefits. A natural, ecofriendly and green chemistry solution incorporating
mycology, biotechnology and nanotechnology is the
fungal synthesis of noble metal nanoparticles such as
silver nanoparticles. There are several methods
including physical, chemical and biological methods that
can be used for the synthesis of silver nanoparticles. The
aim of this research is to implement the green
production of silver nanoparticles, i.e., the biological
method using penicillium rubensaqueous fungal extract.
The aqueous fungal extract was added to silver nitrate
solution where the color of the silver nitrate reaction
medium was changed from Pale yellow to brown which
indicates reduction of silver ions to silver
nanoparticles.Synthesized silver nanoparticles are thus
characterized by UV-Visible spectroscopy, which
disclose a peak of 400-420 nm. The Fourier transform
infrared spectrum was studied in order to distinguish
the effective functional molecules responsible for the
reduction and stabilization of fungal synthesized silver
nanoparticles.
Changes in parameters such as pH, temperature and
silver nitrate solution concentration were used to
optimize the output of silver nanoparticles and to assess
absorption in UV-Visible spectrophotometer. It is
therefore concluded that the biosynthesis of silver
nanoparticles using extracellular fungal filtrate was
simple, eco-friendly and robust. Effective degradation of
Methylene blue dye in 90 minutes of exposure time was
observed, providing 97 percent efficiency.
