Dual-emission MOF-based ratiometric platform and sensory hydrogel for visible detection of biogenic amines in food spoilage

Pei Jia et al.

Summary: This study developed a simple and effective method for visual identification of biogenic amines (BAs) in perishable seafood using dual-emissive metal-organic framework probes and color-transition hydrogels. The functionalized Ru@UiO-OH was prepared by encapsulating Ru(bpy)32+ into UiO-OH. The fluorescence intensity of Ru@UiO-OH at 537 and 600 nm showed different changes in the presence of trimethylamine (TMA), resulting in a noticeable color change. Ru@UiO-OH was loaded into hydrogels that acted as sniffing trademarks to detect volatile TMA vapor, which could be quantified using a smartphone-based readout. The practical applicability of the fluorescent sensory hydrogels was confirmed through experiments on shrimp and fish spoilage, with results consistent with the standard method for detecting total volatile basic nitrogen. This research holds great significance for accurately sensing seafood freshness in a straightforward manner.

Determination of trace amount of iron cations using electrochemical methods at N, S doped GQD modified electrode

S. Kalhori et al.

Summary: In this study, nitrogen and sulfur co-doped graphene quantum dot-modified glassy carbon electrodes were used to detect iron cations in aqueous solutions. Electrochemical techniques such as cyclic voltammetry, square wave voltammetry, and hydrodynamic amperometry were employed to study the electrochemical behavior and determination of Fe cations. The presence of free electrons in the structure of the modified electrode facilitated electron transfer reactions, resulting in increased sensitivity and lower limit of detection. Under optimized conditions, the amperometric response showed a linear range from 1 to 100 nM of Fe(III) with a detection limit of 0.23 nM. The method was successfully applied to determine Fe(III) in drug and water real samples, demonstrating its validity and applicability. This sensor based on doped nanoparticles opens up a new platform for highly sensitive and selective detection of analytes.
