- •
The fluorescent sensor based on MMIP for the detection of atrazine was developed.
- •
The testing principle is based on competition between atrazine and fluorochrome.
- •
Fluorescence changes are linearly related to the logarithm of atrazine concentration.
- •
The detection limit for atrazine was 0.58 μM and recoveries were 77.6–115%.
