A new fluorescence immunoassay (FIA) accurately detects cocaine. This method offers a sensitive detection range and minimal interference from related compounds, making it a valuable tool for cocaine analysis.

Area of Science:

  • Analytical Chemistry
  • Biochemistry
  • Forensic Science

Background:

  • Accurate detection of cocaine is crucial for clinical and forensic applications.
  • Existing immunoassay methods may face challenges with sensitivity or specificity.
  • Development of novel detection techniques is essential for improved cocaine analysis.

Purpose of the Study:

  • To develop and validate a fluorescence immunoassay (FIA) for cocaine detection.
  • To assess the sensitivity, detection range, and specificity of the developed FIA.
  • To evaluate the potential of the FIA as a tool for cocaine analysis.

Main Methods:

  • Development of a fluorescence immunoassay (FIA) using merocyanine-labeled norcocaine and a monoclonal antibody specific to cocaine.
  • Determination of the detection range and limit of detection for cocaine using the FIA.

  • Assessment of cross-reactivity with other cocaine derivatives to evaluate specificity.

    • Main Results:

    • The developed FIA demonstrated a cocaine detection range of 20.0 to 1700 μg/L.
    • The limit of detection for cocaine was determined to be 20.0 μg/L.
    • Minimal interference from other cocaine derivatives was observed, with cross-reactivity values below 20%.

    Conclusions:

    • The developed fluorescence immunoassay (FIA) is a sensitive and specific method for cocaine detection.
    • The FIA exhibits a wide detection range and low limit of detection, suitable for practical applications.
    • This FIA represents a useful tool for the reliable detection of cocaine in various settings.
