This review focuses on recent contributions in the development of the electrochemical sensors based on carbon nanotubes (CNTs). CNTs have unique mechanical and electronic properties, combined with chemical stability, and behave electrically as a metal or semiconductor, depending on their structure. For sensing applications, CNTs have many advantages such as small size with larger surface area, excellent electron transfer promoting ability when used as electrodes modifier in electrochemical reactions, and easy protein immobilization with retention of its activity for potential biosensors. CNTs play an important role in the performance of electrochemical biosensors, immunosensors, and DNA biosensors. Various methods have been developed for the design of sensors using CNTs in recent years. Herein we summarize the applications of CNTs in the construction of electrochemical sensors and biosensors along with other nanomaterials and conducting polymers.
本文综述了基于碳纳米管（CNTs）的电化学传感器的最新研究进展。CNTs 具有独特的力学和电子性能，同时还具有化学稳定性，其电学性能可以表现为金属或半导体，这取决于其结构。在传感应用中，CNTs 具有许多优点，例如尺寸小但表面积大，在作为电极修饰剂用于电化学反应时具有优异的电子转移促进能力，并且易于固定蛋白质而保留其用于潜在生物传感器的活性。CNTs 在电化学生物传感器、免疫传感器和 DNA 生物传感器的性能中发挥着重要作用。近年来，已经开发了各种使用 CNTs 设计传感器的方法。本文总结了 CNTs 与其他纳米材料和导电聚合物一起在电化学传感器和生物传感器构建中的应用。
