ABSTRACT

Dopamine (DA) is biologically important molecule, which plays a vital role in hormonal, renal, cardiovascular, and central nervous systems. Since abnormal level of this biological molecule leads to several diseases, its accurate and fast monitoring is of great importance for clinical diagnosis and treatment. The electrochemical approaches have become of significant interest to fulfill the requirements of DA detection. The electrode modifications play a crucial role in sensitive and selective detection of DA. This review presents the progress of poly(3,4-ethylenedioxythiophene) (PEDOT)-based materials modified electrodes for electrochemical determination of DA in the presence of interferents such as AA and UA.

摘要

多巴胺（DA）是生物学上重要的分子，在激素，肾，心血管和中枢神经系统中起着至关重要的作用。由于该生物分子的异常水平导致多种疾病，因此其准确和快速的监测对于临床诊断和治疗非常重要。电化学方法已成为满足DA检测要求的重要兴趣。电极修饰在DA的灵敏和选择性检测中起着至关重要的作用。这项审查介绍了基于聚（3,4-乙撑二氧噻吩）（PEDOT）的材料修饰的电极在存在诸如AA和UA等干扰物的情况下电化学测定DA的研究进展。
