Abstract:

Green nano-biotechnology refers to the production of stable nanoparticles through biological routes. Synthesis of nanoparticles by the use of fungi especially mushrooms plays a key role in large scale production of nanoparticles in less time. Fungi contain many enzymes and proteins involved in the synthesis of NPs. These are simpler to grow and also their yield is high. This study reports on the synthesis of iron nanoparticles using a green synthesis method that involves use of aqueous extract of Agaricus bisporous as reducing/capping agents. The nanoparticles were synthesized by varying the volume of mushroom extract used as well as by using different concentrations of metal salt under different temperature conditions. The synthesized nanoparticles were characterized using dynamic light scattering (DLS) and Fourier transform infrared spectroscopy (FTIR). The antifungal activities of the synthesized nanoparticles were also evaluated. The results showed that the green synthesis method was effective in producing iron nanoparticles with an average size of 80 nm. The DLS analysis indicated a relatively narrow size distribution of the nanoparticles synthesized under high temperature conditions where as those synthesized under room temperature conditions showed broader size distribution. The FTIR analysis confirmed the presence of iron oxide in the synthesized nanoparticles. Furthermore, the synthesized nanoparticles exhibited significant antifungal activities against Aspergillus flavus. The nanoparticles showed some antifungal potential that was lower than the control drug (Dermosporin) which is a broad spectrum antimycotic drug.
