Summary
A novel dual-signal microfluidic method enhances food safety by enabling sensitive detection of multiple mycotoxins like Deoxynivalenol (DON) and Ochratoxin A (OTA). This automated system offers rapid, efficient, and accurate mycotoxin analysis in complex food samples.
Area of Science:
- Analytical Chemistry
- Food Science
- Biotechnology
Background:
- Mycotoxin contamination poses significant risks to food safety and consumer health.
- Sensitive and rapid detection methods are crucial for monitoring mycotoxins in food products.
- Existing methods can be time-consuming and require specialized expertise.
Purpose of the Study:
- To develop a highly sensitive chemiluminescent/colorimetric dual-signal readout microfluidic method for detecting multiple mycotoxins.
- To integrate a streptavidin-biotin-alkaline phosphatase (SA-Biotin-ALP) signal amplification system for enhanced detection.
- To create a dual-mode microfluidic workstation (DMMW) for automated and rapid mycotoxin analysis.
Main Methods:
- Indirect competitive enzyme-linked immunoassay (ic-ELISA) integrated into a microfluidic chip.
- Utilized a SA-Biotin-ALP signal amplification system.
- Developed a DMMW for automated sample processing and detection.
Main Results:
- Sensitive detection ranges achieved: DON (4-128 ng/mL), OTA (2-64 ng/mL), AFB1 (0.2-6.4 ng/mL).
- Low limits of detection (LOD): DON (2.636 ng/mL), OTA (1.492 ng/mL), AFB1 (0.131 ng/mL).
- High recovery rates (91.93%-109.31%) in beer samples, demonstrating matrix applicability.
Conclusions:
- The proposed microfluidic method offers high sensitivity and efficiency for detecting multiple mycotoxins.
- The automated DMMW simplifies procedures, reduces analysis time, and requires less specialized personnel.
- This technology shows significant potential for rapid, on-site mycotoxin detection in complex food matrices.
