Summary
A new portable electrochemiluminescence (ECL) platform using machine learning enables sensitive detection of zearalenone (ZEN), a mycotoxin found in cereals. This technology offers a scalable solution for rapid food safety monitoring.
Area of Science:
- Analytical Chemistry
- Food Science
- Biotechnology
Background:
- Zearalenone (ZEN) is an estrogenic mycotoxin from Fusarium fungi, prevalent in cereals like wheat, rice, and maize.
- ZEN exposure poses risks, causing endocrine disruption and reproductive issues, necessitating reliable detection methods.
Purpose of the Study:
- To develop a portable, image-based electrochemiluminescence (ECL) platform for quantitative analysis of zearalenone (ZEN).
- To integrate a micropillar electrode design with machine learning for enhanced ZEN detection.
Main Methods:
- Fabrication of a portable ECL platform using luminol-functionalized Zr-based metal-organic frameworks (Zr@Lu-MOFs) on micropillar electrodes.
- Smartphone-based image acquisition of ECL signals, converted to RGB data for analysis.
- A two-step machine learning workflow involving K-nearest neighbor (KNN) classification and Gaussian process regression (GPR) for quantification.
Main Results:
- The platform achieved sensitive ZEN quantification across a wide linear range (0.0001–100 ng/mL) with a low limit of detection (LOD) of 0.23 pg/mL.
- Demonstrated high signal uniformity, reproducibility, and reliable performance in real food samples.
- The image-driven analytical strategy proved effective for scalable and portable analysis.
Conclusions:
- Integrating ECL microarrays with image-level data analysis offers an effective approach for developing scalable and portable analytical platforms.
- This method provides a promising tool for efficient and reliable food safety monitoring, particularly for mycotoxin detection.
