Abstract
The present work describes the biofabrication of highly stable, water-dispersible mycogenic silver/silver (I) oxide nanoparticles (Ag/Ag2O NPs) alongside its potential applications in non-enzymatic electrochemical glucose sensing and catalytic degradation of methylene blue (MB) dye in presence of reducing agent NaBH4. These Ag/Ag2O NPs were fabricated from silver oxide micro powder using endophytic fungus Fusarium oxysporum based environmentally friendly, bio-inspired, top-down approach which is highly reproducible, reliable, and cheap. Bacterial and plant-mediated bottom-up approaches have been previously reported for the production of Ag/Ag2O NPs. Bacterial methods are not economical as they require expensive sophisticated instruments for separation and purification. Similarly, plant-based means of synthesis are not reliable and reproducible due to geographical and seasonal variability's. UV-Visible spectroscopy, TEM, SAED, FTIR, XRD, TGA, and DSC were used for the characterization and investigation of thermal properties of mycogenic nanoparticles and their antimicrobial activity was evaluated by filter- paper bioassay technique.
