The determination of 1-chloro-2,4-dinitrobenzene (CDNB) was used as a proof-of-concept to a simple analytical practical configuration applying magnetic molecularly imprinted particles (mag-MIPs). Mag-MIPs were captured from an emulsion by a home-made magneto-sensor (where a small magnet was entrapped by a graphite-epoxy composite) and then, this sensor, was transferred to the solution containing the analyte, where, after binding to the mag-MIPs, the analyte was directly analysed using differential pulse voltammetry (DPV) since the magneto-sensor acted as the working electrode. After optimization, a detection limit of 6.0 μmol L⁻¹ with a RSD of 2.7% was achieved along with suitable recoveries and selectivity. This methodology offers a different approach for electroanalytical methodologies using mag-MIPs.

1-氯-2,4-二硝基苯（CDNB）的测定用作应用磁性分子印迹粒子（mag-MIPs）的简单分析实用配置的概念验证。通过自制的磁传感器（其中的小磁体被石墨-环氧复合材料包裹）从乳液中捕获了Mag-MIP，然后将该传感器转移到含有分析物的溶液中，然后与在mag-MIPs中，由于磁传感器充当工作电极，因此使用差分脉冲伏安法（DPV）直接分析了分析物。优化后，达到了6.0μmolL ^-1的检出限，相对标准偏差为2.7％，同时具有适当的回收率和选择性。该方法为使用mag-MIP的电分析方法提供了另一种方法。
