In Senegal, Aspergillus flavus, which develops on crops by producing aflatoxins, seriously affects the economy and the health of consumers. In this study, the antifungal effect of silver@silica on aflatoxigenic A. flavus was investigated. An aflatoxigenic A. flavus strain was isolated on Potato Dextrose Agar (PDA) medium from infested groundnut seeds. silver@silica nanoparticles were synthesized by reverse microemulsion and different concentrations of them were tested on A. flavus. The bioactivity type of silver@silica nanoparticles was also determined. The obtained results revealed that strong inhibition of A. flavus was noticed at all concentrations. Additionally, the bioactivity tests performed showed that silver@silica nanoparticles had a fungicide effect on A. flavus. Thus, silver@silica nanoparticles could be used as effective, safe and ecofriendly antifungals to prevent fungal growth and subsequent aflatoxins production.
