摘要

二脲(DU)是一种毒性高、持久性强的棉花落叶剂,对环境构成严重威胁。DU具有电惰性和抗氧化性,识别元素种类少,因此其灵敏度和特异性检测至关重要。本文通过将内空多孔的金纳米笼(AuNCs)与具有大比表面积和优异导电性的氨基官能化还原氧化石墨烯纳米片(NH2-rGO)相结合,开发了一种新型的分子印迹聚合物电化学传感器(MIP-EC)。然后,通过电聚合作用在改性电极上直接生长 DU-MIP,其印迹因子高(6.91),可重复使用性高(至少 5 次)。值得注意的是,NH2-rGO/AuNC 纳米复合材料还能提高 DU-MIP 的识别效率,改善 MIP-EC 传感器的分析性能,使其检测限降至 4.3 ng/mL。此外,该传感器还具有高选择性和快速洗脱/重组的特点,而且构建过程简单,可用于检测棉花和土壤中的 DU。

Molecularly Imprinted Electrochemical Sensor Based on the Self-Assembly of Cage-like Gold Nanoparticles and Amino-Functionalized rGO for the Detection of Diuron in Cotton Defoliant

Diuron (DU) is a kind of cotton defoliant with high toxicity and strong persistence that poses a serious environmental threat. DU has electroactive inertness and oxidation resistance, and there are only a few types of recognition elements, making its sensitive and specific detection critical. Herein, a novel molecularly imprinted polymer-based electrochemical (MIP-EC) sensor was developed by combing gold nanocages (AuNCs) with hollow-interior and porous walls with amino-functionalized reduced graphene oxide nanosheets (NH2-rGO) with a large surface area and excellent conductivity. Then, DU-MIP was directly grown on the modified electrode by electropolymerization, while it displayed a high imprinted factor (6.91) and high reusability (at least 5 times). Significantly, the NH2-rGO/AuNC nanocomposite could also enhance the recognition efficiency of DU-MIP, improving the analytical performances of the MIP-EC sensor, with the detection limit down to 4.3 ng/mL. In addition, this sensor exhibited high selectivity and rapid elution/recombination, and a simple construction process was utilized to detect DU in cotton and soil.
