Broad-spectrum pesticide screening by multiple cholinesterases and thiocholine sensors assembled high-throughput optical array system.
TL;DR: The screening of unknown real contaminated samples were successfully operated, and the screened pesticide species and concentrations were consistent with high-performance liquid chromatography, demonstrating the feasibility of replacing existing complex mass spectrometry-based screening strategy with simple optical analysis.
