Organophosphorus pesticides can prevent or eliminate various pathogenic bacteria, insects, and weeds, and thus they are widely applied in agricultural production. However, illegal use and issues with organophosphorus pesticide residues contribute to global environmental pollution and pose a threat to public health safety. In this study, we developed a sensitive glyphosate (Glyp) fluorescence detection method using papain-stabilized gold nanoclusters (papain-AuNCs) as the fluorescence probe and a tyrosinase (TYR)/dopamine (DA) fluorescence-quenching system.

- Functional DNAs-functionalized magnetic beads (MBs) can improve bioanalysis by enhancing target recognition and enabling magnetic separation, but common issues with DNA probes limit their effectiveness.
- To address these challenges, the study introduces TETapt-tet MBs, a novel DNA tetrahedron nanostructure that uses aptamers for improved detection of tetracycline (TET) through a target-responsive fluorescence method.
- The new method shows enhanced accuracy and sensitivity, achieving low detection limits for TET in honey samples, and can be adapted to detect other antibiotics by changing aptamer sequences, suggesting its potential for food safety applications.
