| dc.description.abstract | Nanoparticles have great potential in the fields of biomedicine, building materials, environmental protection, antibacterial and antifungal agents. Silver sulfide nanoparticles (Ag2S NPs) have been synthesized for their applications in various fields including photoconductors, photovoltaic cells, solar selective coatings and infrared detectors, but have less reporting as bio-compatible material or in in vitro or in vivo applications. Silver sulfide has been hypothesized as less toxic form in nature as metal nanoparticles of soft nature get their ultimate fate by sulfidation as their natural pathway of detoxification. In this study we synthesized silver sulfide nanoforms by approaching sonochemical method. Various sulfide ion sources and silver nitrate were used as initial components for the synthesis of silver sulfide nanoparticles (Ag2S NPs). All the synthesized samples were tested for their preliminary in vitro antifungal activity against Ustilago hordei, Uromyces viciafabia, Fusarium moniliforme and Bipolaris oryzae . Ag2S-4 NPs synthesized from sodium sulfide showed better antifungal potential in comparsion to silver nanoparticles (Ag NPs) and commercially used standard fungicides. The Ag2S-4 NPs sample was further coated with chitosan to get chitosan decorated silver sulfide nanoparticles to evaluate the antifungal potential of this conjugate in comparison to Ag2S NPs. | en_US |
