摘要

电化学传感器是一类以电极为换能器元件的传感器。在这类传感器中,电极是作为固定生物分子和电子运动的固体支撑的关键部件。电极的材料、制造方法和设计会影响电极的结构和特性,最终决定生物传感器的性能,包括灵敏度、选择性、检测极限和动态范围。它们还会影响生物传感器的成本、可制造性、可抛弃性和测量能力。这篇综述文章介绍了在电化学生物传感器中使用非改性和改性电极作为支持物测定生物分子的最新进展。文章总结了使用碳质材料、导电聚合物、MXenes 和过渡金属氧化物纳米材料改性电极的最新研究成果。报告还重点介绍了当前的技术、材料类型、设计、模拟研究以及未改性和改性电极的制造方法。最后,还指出了电化学传感器所面临的挑战,并全面介绍了未来的发展方向。

Recent advances in electrochemical biosensors for the determination of biomolecules on modified and unmodified electrodes

Recent advances in electrochemical biosensors for the determination of biomolecules on modified and unmodified electrodes

Electrochemical sensors are a class of sensors in which the electrode is the transducer element. In this type of sensor, an electrode is a critical component employed as a solid support for immobilizing biomolecules and electron movement. The material, fabrication approach, and design affect the electrode’s structure and properties, which ultimately determine the biosensor’s performance, including sensitivity, selectivity, limit of detection, and dynamic range. They also influence the biosensor’s cost, manufacturability, disposability, and measurement capabilities. This review article describes recent advances in using non-modified and modified electrodes as support in electrochemical biosensors for the determination of biomolecules. It summarizes recent work on modifying electrodes using carbonaceous materials, conducting polymers, MXenes, and transition metal oxide nanomaterials. It also focuses on current techniques, types of materials, designs, simulation studies, and fabrication methods on unmodified and modified electrodes. Lastly, challenges in electrochemical sensors were identified, and future directions were presented comprehensively.
