A molecularly-imprinted electrochemiluminescence sensor was constructed for the determination of fenpropathrin (FPT) by molecular imprinting technology. In this sensing platform, the introduction of CdS@MWCNTs significantly enhanced the initial ECL signal of the luminol-O₂ system. Specifically, MWCNTs was used as a carrier to adsorb more CdS, in which CdS acted as a co-reaction promoter for luminescence. Molecularly imprinted polymer (MIP) containing specific recognition sites of FPT was used as the material for selective recognition. With increasing amount of FPT the ECL signal decreased. Under the optimum conditions, the ECL response was linearly related to the logarithm of FPT concentration. The developed ECL sensor allowed for sensitive determination of FPT and exhibited a wide linear range from 1.0 × 10^− 10 mol L^− 1 to 1.0 × 10^− 6 mol L^− 1. The limit of detection was 3.3 × 10^− 11 mol L^− 1 (S/N = 3). It can be used for the detection of FPT in vegetable samples.

构建了分子印迹电化学发光传感器，用于利用分子印迹技术测定甲氰菊酯（FPT）。在此传感平台中，CdS@MWCNT的引入显着增强了鲁米诺-O ₂系统的初始ECL信号。具体来说，多壁碳纳米管被用作载体来吸附更多的CdS，其中CdS充当发光的共反应促进剂。含有FPT特异性识别位点的分子印迹聚合物（MIP）被用作选择性识别的材料。随着 FPT 量的增加，ECL 信号减弱。在最佳条件下，ECL响应与FPT浓度的对数呈线性相关。开发的ECL传感器可以灵敏地测定FPT，并表现出从1.0 × 10 ^{− 10} mol L ^{− 1}到1.0 × 10 ^{− 6} mol L ^{− 1}的宽线性范围。检测限为 3.3 × 10 ^{− 11} mol L ^{− 1} (S/ N  = 3)。可用于蔬菜样品中FPT的检测。
