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.

A ratiometric fluorescent tag based on dual-emissive hydrophobic carbon dots for in-situ monitoring of seafood freshness

Wenyang Zhang et al.

Summary: A ratiometric fluorescent tag based on dual-emissive hydrophobic carbon dots (H-CDs) was developed for the real-time and visual evaluation of seafood freshness by responding to volatile base nitrogens (VBNs). The tag showed a sensitive response to VBNs, with a limit of detection of 7 μM for spermine and 137 ppb for ammonia hydroxide. The tag, deposited on cotton paper, exhibited clear color variations from red to blue under UV light upon treatment with ammonia vapor. The cytotoxicity of the H-CDs was also evaluated and found to be non-toxic. This is the first ratiometric tag using dual-emissive CDs with aggregation-induced emission properties for the recognition of VBNs and seafood freshness in real-time and visual manner.
