Abstract

Antimicrobial resistance poses a significant challenge to public health, and is worsened by the widespread misuse of antimicrobial agents such as triclosan (TCS) in personal care and household products. Leveraging the electrochemical reactivity of TCS's phenolic hydroxyl group, this study investigates the electrochemical behavior of TCS on a Cu-based nano-metal-organic framework (Cu-BTC) surface. The synthesis of Cu-BTC via a room temperature solvent method, with triethylamine as a regulator, ensures uniform nanoparticle formation. The electrochemical properties of Cu-BTC and the signal enhancement mechanism are comprehensively examined. Utilizing the signal amplification effect of Cu-BTC, an electrochemical sensor for TCS detection is developed and optimized using response surface methodology. The resulting method offers a simple, rapid, and highly sensitive detection of TCS, with a linear range of 25-10,000 nM and a detection limit of 25 nM. This research highlights the potential of Cu-BTC as a promising material for electrochemical sensing applications, contributing to advancements in environmental monitoring and public health protection.

摘要

抗菌耐药性对公共卫生构成了重大挑战，而个人护理和家用产品中三氯生（TCS）等抗菌剂的广泛滥用则使这一问题更加恶化。本研究利用三氯生酚羟基的电化学反应性，研究了三氯生在铜基金属有机框架（Cu-BTC）表面的电化学行为。通过室温溶剂法合成Cu-BTC，并以三乙胺作为调节剂，确保形成均匀的纳米颗粒。全面研究了Cu-BTC的电化学性质和信号增强机制。利用Cu-BTC的信号放大效应，采用响应面法开发并优化了一种用于检测三氯生的电化学传感器。所得方法提供了一种简单、快速且高度灵敏的三氯生检测方法，线性范围为25-10000 nM，检测限为25 nM。本研究突出了Cu-BTC作为一种有前景的电化学传感应用材料的潜力，为环境监测和公共卫生保护的进步做出了贡献。
