In this study, silver nanoparticles were synthesized using the fungus, Aspergillus flavus at high yield with an aqueous solution of AgNo3. The formation of silver nanoparticles was confirmed using UV-visible spectrophotometer and their presence was displayed by XRD studies. The size and place formation of silver nanoparticles were investigated using Scanning Electron Microscopy (SEM).
