Summary: This research aimed to develop an electrochemical sensor for sensitive and selective determination of trace levels of PFOS in environmental water. The sensor utilized a glassy carbon electrode modified with gold nanoparticles and a molecularly imprinted polymer via electro-polymerization of dopamine with PFOS as the template. A new method for PFOS determination was established using differential pulse voltammetry. The sensor showed good recognition performance, a linear detection range of 0.01-8.00 μmol/L, and a detection limit of 0.0042 μmol/L.

Summary: A novel electrochemical sensor was developed for the recognition and detection of tartrazine. The sensor showed a large and specific response to tartrazine due to the synergistic effect of the strong electrocatalytic activity of PtCo nanoalloy-decorated graphene oxide and the high tartrazine recognition ability of the imprinted cavities. The sensor exhibited good performance in terms of detection limit, anti-interference ability, stability, and reproducibility, and was successfully applied to detect tartrazine in spiked food samples.

Summary: This study investigated the use of nanocomposite hydrogels containing bentonite clay nanoparticles for the removal of methyl violet dye. The results showed that the nanoparticles were successfully distributed in the hydrogel system, and a 10 wt. % concentration of bentonite nanoparticles achieved the highest dye adsorption efficiency. The thermodynamics studies indicated that the adsorption process was spontaneous, and the adsorption process was exothermic using both types of adsorbents. The Langmuir isotherm model was successfully used to describe the equilibrium behavior, and the pseudo-second-order model provided the best description of the kinetic behavior.

Summary: The potential of two identified probiotic strains, ABRIIFBI-6 and ABRIIFBI-7, to inhibit the growth of aspergilli and reduce aflatoxin availability was investigated. Both strains survived in simulated gastrointestinal conditions and significantly inhibited Aspergillus growth. They also exhibited high auto-aggregation, hydrophobicity, and coaggregation abilities with other bacteria. These findings contribute to the understanding of LAB probiotic potential in dairy products and their use as biocontrol agents against aflatoxin-producing species.

Summary: For the first time, a dispersive micro-solid phase extraction (D-mu SPE) based on graphene oxide was used for the ultrasensitive determination of Cd. With this method, Cd can be efficiently extracted from a mixture of alkali and alkaline earth metals without the need for an elution step. The combination of D-mu SPE and SAGD OES significantly reduces matrix effects and improves the tolerance of Cd to alkali metals. The method shows simplicity in the measurement system and the commercially available nanosorbent used.

Summary: This work proposes a rapid and sensitive spectroscopic method for detecting melamine in food products using rare-earth Terbium-doped Graphene Quantum Dots (Tb-GQDs) synthesized by microwave and simple chemical conjugation methods. The synthesized Tb-GQDs show a spherical shape with a size of approximately 6 nm and a quantum yield of 52%. The maximum detection limit for melamine concentration in milk and milk products is found to be 0.31 μM. The dual emitting Tb-GQDs provide a sensitive and effective platform for real-time detection of melamine in food samples, particularly in milk, and show promising potential in the food industry.
