Food Safety
PubMedThe corn, peanuts, or grain in your pantry could carry invisible mold toxins that cause liver cancer — this new detection method could help farmers and food producers catch contamination before it reaches your kitchen.
Aflatoxin B1 is a poison made by certain molds that grow on crops, especially in warm or humid conditions. Researchers built a sensor that glows differently when the toxin is present, like a chemical alarm light. This could help detect dangerous contamination in food much faster and more cheaply than current lab tests.
Key Findings
The fluorescence polarization method can detect aflatoxin B1 by sensing changes in molecular rigidity when the toxin binds to a probe molecule
The approach offers a rapid, sensitive alternative to traditional detection methods that require extensive lab processing
Rigidity-responsive signaling enables detection without complex equipment, potentially supporting field-level food safety testing
chevron_right Technical Summary
Scientists developed a new fluorescence-based method to detect aflatoxin B1, a dangerous mold toxin that contaminates crops like corn and peanuts. The technique uses changes in light polarization to signal the toxin's presence quickly and sensitively.
