Overview

A biosensor detects fumonisin B1 in food samples, indicating a reliable method for mycotoxin analysis.

Key Points

  • The research aims to develop an efficient biosensor for the rapid detection of fumonisin B1 using aptamers.
  • Developed a biosensor utilizing plasmamodified graphene oxide as a fluorescence quencher.
  • Employed an aptamer labeled with 5-carboxyfluorescein for specific binding to fumonisin B1.
  • Measured fluorescence recovery and intensity to quantify FB1 levels across a wide concentration range.
  • Achieved linear detection of FB1 from 10 to 5 × 10^6 ng/L.
  • Detection limit of 0.16 μg/L shows high sensitivity.
  • Exhibited strong specificity for FB1 among six other mycotoxins with recovery rates in food samples between 89.3% and 104.7%.
