Development of a colloidal gold-based strip test for the detection of chlorothalonil residues in cucumber
Year: 2015
Type: article
Abstract: An immunochromatographic lateral flow strip test using the competitive format was developed for the determination of chlorothalonil (CTN) residues in cucumber. The limit of detection was less than 100 ng/mL by visual assessment and was found to be 91.78 ± 0.17 ng/mL for quantitative detection using a test strip reader. The recoveries of test samples were from 89.26% to 102.02% and the coefficient of variation (%) was less than 4.75%. Parallel analysis of cucumber samples with CTN showed comparable results from the strip test and high performance liquid chromatography. The strip test requires 5–8 min to complete and provides a very useful screening method for the quantitative and qualitative detection of CTN residues in cucumber.
