Overview

Ternary PEC probe improves chlorpyrifos detection in complex samples, highlighting dual charge-transfer and biosensing effectiveness.

Key Points

  • The optimized Pd/CdS@Co3S4 nanocomposite enhances photocurrent by ~5 times compared to its individual components.
  • AChE-immobilized biosensor quantifies chlorpyrifos through competitive electron consumption, showing exceptional sensitivity.
  • The sensor achieves a linear dynamic range of 0.1 to 2000 ng·mL−1 for chlorpyrifos detection, indicating broad adaptability.
  • With a low detection limit of 0.05 ng·mL−1, it demonstrates outstanding accuracy and stability for real samples.
