Abstract: -

In nanotechnology, the synthesis of nanoparticles by using the microbes is a boon for advanced research. In this study, silver nanoparticles were synthesized using the fungus Aspergillus fumigatus with an aqueous solution of AgNO3. Synthesized silver nanoparticles (Ag-NPs) were characterized by UV-visible spectrophotometer. Maximum absorbance was observed at 435 nm in a visible region. The reduction of silver ions was due to amino groups of proteins and other functional groups in the cell-free filtrate of fungi. The formation of stable protein capped with the silver nanoparticles because of reduction of silver ion. The Ag-NPs possess potent antimicrobial activity against Bacillus cereus, Bacillus subtilis, Klebsiella pneumoniae and Pseudomonas aeruginosa.

Keywords:  Silver nanoparticles (AgNPs), Aspergillus fumigatus, UV-Visible spectrophotometer, Antimicrobial activity.
