Summary
This summary is machine-generated.

A new fluorescence sensor detects the veterinary drug Diclazuril (DIC) in poultry products. This sensor offers sensitive, rapid, and visual detection, enhancing food safety for consumers.

Area of Science:

  • Materials Science
  • Analytical Chemistry
  • Food Science

Background:

  • Diclazuril (DIC) is a triazine-class drug extensively used in poultry farming to combat coccidiosis.
  • Overuse of DIC can lead to its accumulation in animal tissues, posing potential risks to human health through the food chain.
  • Sensitive and reliable detection methods for DIC in food products are crucial for ensuring food safety.

Purpose of the Study:

  • To develop a stable and sensitive fluorescence sensor for the detection of Diclazuril (DIC).
  • To evaluate the sensor's performance in detecting DIC in real-world food matrices like chicken and eggs.
  • To create an instrument-free, rapid detection system for DIC in animal-derived food products.

Main Methods:

  • Fabrication of a Europium (Eu³⁺)-doped UiO-66 metal-organic framework (MOF) based fluorescence sensor, designated EuUHIPA-30.

  • Testing the sensor's selectivity against 20 different veterinary drugs.
  • Assessing the sensor's detection limit, response time, recyclability, and recovery rates in chicken and egg samples.
  • Development of a smartphone-integrated paper-based sensor for visual and intelligent DIC detection.

    • Main Results:

    • The EuUHIPA-30 sensor exhibited selective fluorescence response exclusively to Diclazuril (DIC) among tested veterinary drugs.
    • Achieved a low detection limit of 0.19 μM for DIC with a rapid response time of 10 seconds.
    • Demonstrated good recyclability and high recovery rates for DIC detection in chicken and egg samples.
    • A smartphone-based paper sensor enabled instrument-free, rapid, and visual detection of DIC.

    Conclusions:

    • EuUHIPA-30 serves as a highly selective and sensitive fluorescence sensor for Diclazuril (DIC).
    • The developed sensor and integrated paper-based system are suitable for practical, on-site detection of DIC in animal-derived foods.
    • This approach significantly contributes to enhancing food safety by monitoring residual veterinary drug levels.
