Summary: Using the zebrafish model, this study aimed to clarify the potential mechanisms governing the resistance and resilience of gut microbiota after exposure to silver nanoparticles (AgNPs). The exposure to AgNPs significantly reduced the a-diversity of gut microbiota and led to noticeable changes in community composition. Resilience and resistance of gut microbiota responses to AgNPs may be determined by key taxa such as Acinetobacter and Gemmata, offering new insights into maintaining stability during environmental perturbations.

Summary: Titanium dioxide (TiO2) nanoparticles have been found to have adverse effects on gut bacteria and host metabolism, as shown in both in vitro and in vivo studies. The nanoparticles inhibit the growth of beneficial gut bacteria and cause damage to their cell membranes, leading to changes in metabolic pathways related to gut and host health. In mice, feeding on TiO2 nanoparticles affects the tryptophan metabolism pathway and reduces the levels of neuroprotective metabolites. Understanding the relationship between gut bacteria composition and metabolism is crucial for toxicological assessment of food components.

Summary: The study evaluated the potential of entomopathogenic fungi isolates to synthesize silver nanoparticles, showing significant variations in pathogenicity, virulence, and biomass production among the isolates, with only one isolate unable to synthesize silver nanoparticles. Pearson's correlation analysis revealed significant negative correlations between virulence x biosynthesis potential and biomass production x biosynthesis potential. This indicates that AgNPs with entomopathogenic fungus extract can be used to produce an innovative bioinsecticide product through a green production process.

Summary: This study demonstrates the selective optical, fluorescent, and electrochemical detection of Zn2+ using silver nanoparticles synthesized with fresh extract of Myristica fragrans. The synthesized nanoparticles showed effective complexation with Zn2+, leading to decreased absorbance and fluorescent intensity. The electrochemical sensor based on these nanoparticles exhibited a low limit of detection for Zn2+ and good sensing ability in environmental water samples. Additionally, the nanoparticles showed catalytic activity towards the reduction of environmental contaminants with rapid degradation achieved within minutes.

Summary: Bio-fabrication of silver, copper, and copper oxide nanoparticles and nanocomposites using medicinal plant species and bacteria may provide a novel alternative strategy to combat multidrug-resistant bacteria. This literature review discusses recent studies and challenges related to the antibacterial and photocatalytic capacities of biosynthesized silver and copper nanoparticles and nanocomposites from two sources. The antibacterial activity and mechanisms, as well as the photodegradation process, are important factors to consider in future investigations.

Summary: Understanding the mechanism of detection is crucial in selecting a suitable fluorophore for the detection of nitroaromatic and non-aromatic high energy materials (HEMs). Conducting polymers, specifically functionalized polyaniline, have shown significance in fluorescence quenching studies. Electrochemical methods help in establishing the probable mechanism associated with the sensing study of HEMs, while FTIR and resonance Raman characterization aid in understanding the interaction between nitro groups and polyaniline.
