OPTIMIZATION OF MYCOSYNTHESIS OF SILVER NANOPARTICLESFROM ASPERGILLUS FLAVUSTriveni Ashok Naik and N. Mallikarjun
Nanotechnology is a multidisciplinary branch of science that deals with the production of materials thatare of size range of 1-100nm. The unique physical and chemical properties of nanoparticles have enabledtheir applications in various fields including optical sensor, imaging, medicine and diagnostics etc. Amongall nanoparticles, silver nanoparticles have found wide applications. There are various methods availablefor biosynthesis of Silver nanoparticles including physical and chemical methods. But these methods areexpensive and are hazardous. The present study focuses on developing an eco-friendly and economicalmethod for synthesis of nanoparticles using Aspergillus flavus. Cell free extract of Aspergillus flavus wastreated with Silver nitrate (AgNO3). The production of nanoparticles was monitored using UV VisibleSpectrophotometer. The biosynthesized nanoparticles were characterized by X-Ray Diffraction (XRD),Scanning Electron Microscope (SEM) and Energy-dispersive X-Ray spectroscopy (EDX). The biosynthesiswas optimized for different parameters such as pH, temperature and AgNO3 concentration.
