What is Biosynthesis of Bt-Ag~2~O nanoparticles using Bacillus thuringiensis and their pesticidal and antimicrobial activities about?
## Abstract Nanosilver oxide exhibits strong antibacterial and photocatalytic properties and has shown great application potential in food packaging, biochemical fields, and other fields involving diseases and pest control. In this study, Ag~2~O nanoparticles were synthesized using __Bacillus thuringiensis__ (Bt-Ag~2~O NPs). The physicochemical characteristics of the Bt-Ag~2~O NPs were analyzed by UV‒vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscope (SEM), inductively coupled plasma emission spectrometry (ICP), high-resolution transmission electron microscopy (HR-TEM), and zeta potential. The phis-chemical characterization revealed that the Bt-Ag~2~O NPs are in spherical shape with the small particle size (18.24 nm), high crystallinity, well dispersity, and stability. The biopesticidal and antifungal effects of Bt-Ag~2~O NPs were tested against __Tribolium castaneum__, __Aspergillus flavus__, and __Penicillium chrysogenum__. The survival, growth, and reproduction of tested pests and molds were significantly inhibited by Bt-Ag~2~O NPs in a dose-dependent manner. Bt-Ag~2~O NPs showed higher pesticidal activities ag
