Aptamer-based colorimetric sensing of acetamiprid in soil samples: Sensitivity, selectivity and mechanism

- A simple, sensitive and selective colorimetric detection of acetamiprid is achieved.
- ABA is employed as recognition element and improves the selectivity remarkably.
- High selectivity comes from the specific interaction between acetamiprid and ABA.
- Acetamiprid detection in real soil samples exhibits good reliability and stability.
