In this paper, novel and stable acetylcholinesterase (AChE) sensor with patterned structure for detecting organophosphorus pesticides (OPs) based on titanium dioxide sol‐gel carrier was proposed and prepared. Biosensor was assembled by dropping titanium oxide, chitosan (CS) and enzyme to the surface of the glass carbon step by step. The concentration range of the sensor detection for dichlorvos (DDVP) is 1.13 nM to 22.6 μM, and the limit of detection (LOD) is 0.23 nM. It can also detect dichlorvos in cabbage juice samples accurately. The preparation of biosensor adopted a patterned novel structure for the first time, which opens a new way for the structure optimization of organophosphorus pesticide sensor.

具有图案结构的乙酰胆碱酯酶传感器，用于检测基于二氧化钛溶胶-凝胶载体的有机磷农药

本文提出并制备了具有图案结构的新颖稳定的乙酰胆碱酯酶（AChE）传感器，用于检测基于二氧化钛溶胶-凝胶载体的有机磷农药（OPs）。通过逐步将二氧化钛，壳聚糖（CS）和酶滴入玻璃碳的表面来组装生物传感器。敌敌畏（DDVP）的传感器检测浓度范围为1.13 nM至22.6μM，检测极限（LOD）为0.23 nM。它还可以准确检测卷心菜汁样品中的敌敌畏。生物传感器的制备首次采用了带图案的新颖结构，为有机磷农药传感器的结构优化开辟了新途径。
