摘要

本文报道了首次利用电位动力学电聚合技术成功制备了PYO印迹聚多巴胺修饰玻碳电极。分子印迹的PDA薄膜比未印迹的聚多巴胺(NIP)在GCE上的电流响应增强。MIP-GCE传感器具有更高的灵敏度，提供10µM至100µM的线性范围(r2 = 0.993)，低检测限(6.45µM)和定量限(21.5µM)。MIP-PDA/GCE是一种灵敏、选择性的电化学PYO传感器。首次制备了PYO印迹聚多巴胺(MIP-PDA)。玻璃碳上的MIP-PDA比非印迹PDA对PYO更敏感。玻璃碳上的MIP-PDA是一种灵敏的，选择性的PYO电化学传感器。

Pyocyanin biomarker imprinted polydopamine for rapid and simple indirect detection of Pseudomonas aeruginosa

This paper reports the first successful preparation of pyocyanin (PYO)-imprinted polydopamine-modified glassy carbon electrodes (PDA-GCE) using potentiodynamic electropolymerization. The molecularly imprinted PDA films showed an enhanced current response to pyocyanin than non-imprinted polydopamine (NIP) on GCE. The MIP-GCE sensor exhibited improved sensitivity, offering a linear range of 10 µM to 100 µM (r2 = 0.993), with a low limit of detection (6.45 µM) and limit of quantitation (21.5 µM). The MIP-PDA/GCE is a sensitive, selective electrochemical sensor for PYO. A pyocyanin (PYO)-imprinted polydopamine (MIP-PDA) was prepared for the first time. The MIP-PDA on glassy carbon is more sensitive to PYO than non-imprinted PDA. The MIP-PDA on glassy carbon is a sensitive, selective electrochemical sensor for PYO.
