Abstract :

[en] Volatileamines (VAs) are critical formeat freshness, yet nondestructive, real-timeVAsdetection remains challenging. Wedevelopedacolorimetric-fluorescentdual-signalbiosensor using single-atom iron nanozyme (SAFe-N-C) and carbon quantumdots (CDs): SAFe-N-Ccatalyzes redTMB to oxTMB, quenchingCDsfluorescenceviainnerfilteringeffect(IFE).VAs reduceoxTMB, recoveringCDfluorescence.Withlowammonia LOD (0.0838 ppm, 0.5-50 ppm range), it enables nondestructive, real-timeVAsmonitoring in livestock/poultry meat,advancingportablefreshnessassessment
