Development of molecularly imprinted polymers-surface-enhanced Raman spectroscopy/colorimetric dual sensor for determination of chlorpyrifos in apple juice
A AgNPs- based colorimetric/SERS dual sensor to determine CPF was developed. MIPs were synthesized by bulk polymerization to extract CPF from apple juice. CPF in apple juice at concentrations ≥5 mg L−1 was detected by naked eyes. UV and Raman spectroscopies quantified CPF in apple juice at 0.1 and 0.01 mg L−1. Rapid determination of trace level of CPF in apple juice was achieved (<25 min).
