Biomass carbon quantum dots and Zr-MOFs as ratiometric fluorescent probes for sensitive detection of biogenic amines in shrimp samples

Key Points

• The central aim is to develop a sensitive method for detecting biogenic amines using new fluorescent probes.
• Utilized biomass carbon quantum dots and Zr-Metal Organic Frameworks (MOFs) as components of the probes.
• Developed a ratiometric fluorescent paper-based detection method.
• Implemented on-site rapid testing for food safety.
• Achieved a dual-response mechanism with one signal increasing and another decreasing.
• Demonstrated high sensitivity in detecting biogenic amines in shrimp samples.
