Zirconium and vanadium bimetallic organic framework nanozyme for bioenzymes-free colorimetric and photothermal dual-mode direct detection of organophosphorus pesticides

Puntos clave

• The aim is to develop a colorimetric and photothermal method for the detection of organophosphorus pesticides using a bimetallic nanozyme.
• Utilized a bimetallic organic framework combining zirconium and vanadium for sensor development.
• Employed colorimetric and photothermal properties in the detection process.
• Conducted comparative analysis with traditional bioenzyme-based methods.
• Achieved successful detection of organophosphorus pesticides without the need for bioenzymes.
• Showed improved sensitivity and efficiency in comparison to typical single-signal methods.
