Implication

Electrochemical aptasensor shows enhanced signal stability and reproducibility for detecting aflatoxin B1, indicating effective food safety applications.

Key Points

An ultrasensitive electrochemical aptasensor detects Aflatoxin B1 with high specificity and stability.
Detection range spans from 1 × 10-4 to 1 × 102 ng/mL, with a limit of detection at 6.3 × 10-5 ng/mL.
This involves bipedal Mg2+-dependent deoxyribonuclease for signal amplification through catalytic hairpin assembly.
The findings highlight potential for broad utilization in food safety monitoring and toxin assessment.
