Summary: Heavy metal ions as metallic pollutants pose a global issue due to their harmful effects on the aquatic ecosystem and human health. Conventional detection methods have limitations, making the development of an efficient method for on-site and real-time detection of heavy metal residues crucial. Aptamer-based sensors, with their high sensitivity, ease of production, simplicity, specificity, stability, low immunogenicity, and cost-effectiveness, offer advantages over antibodies. When combined with nanomaterials, nucleic acid aptamers can selectively bind to metal ions, enabling on-site monitoring of their residues.

Summary: Efficient spread of respiratory viruses requires the virus to maintain infectivity in the environment. Our study measured the impact of initial droplet volume and relative humidity on the stability of influenza A virus, bacteriophage Phi6, and SARS-CoV-2. Virus decay rates differed between the wet and dry phases, and there were differences in virus decay characteristics by droplet size and virus. This study suggests that virus decay in media is related to droplet evaporation, which is controlled by relative humidity.

Summary: In this study, surface-enhanced Raman spectroscopy (SERS) was used to monitor the bioactive metabolites produced by ampicillin-resistant Pseudomonas aeruginosa strains and investigate the mechanisms underlying antibiotic resistance. The results showed that the blue-green pigment pyocyanin (PYO) dominated the metabolite signals and was significantly enhanced in the presence of subminimal inhibitory concentrations of ampicillin. The SERS spectra also revealed minimal impact on the production of intermediate substances and consistent nutrient consumption. Furthermore, exogenously added PYO enhanced the tolerance of ampicillin-susceptible Escherichia coli to some extent, indicating that PYO mediates antibiotic resistance in both the parent species and cocultured bacterial strains. The metabolic SERS signal provides new insights into antibiotic resistance and has promising applications in environmental monitoring and rapid clinical detection.

Summary: This study introduces a facile one-step biosynthesis method for a bilayer structured hydrogel composed of reduced-graphene oxide (rGO) and bacterial nanocellulose (BNC) for various photothermal water treatment applications. The bilayer hydrogel was synthesized by modifying the BNC growth medium with an optimized concentration of corn steep liquor, which acted as a growth enhancer. The resulting rGO-BNC bilayer membrane showed comparable performance with ultrafiltration in terms of particle rejection and water flux, and also demonstrated efficient filtration, photothermal disinfection, and solar water evaporation.
