MXene is a new family of two-dimensional nanomaterials with outstanding electrical conductivity, tunable structure, biocompatibility, and a large surface area. Thanks to these unique physicochemical properties, MXene has been used for constructing electrochemical sensors (MECSens) with excellent performance. In particular, the abundant surface termination of MXene can contribute to greatly enhancing the analytical sensitivity and selectivity of MECSens. Recently, MECSens have been widely applied in many fields including clinical diagnosis, infectious disease surveillance, and food security. However, not all MXene materials are suitable for building electrochemical sensors. In this article, we present an overview of different MECSens that have been developed so far. We begin with a short summary of the preparation and characterization of MECSens. Subsequently, the electrochemical performance, detection strategies, and application scenarios of MECSens are classified and briefly discussed. The article ends with a short conclusion and future perspectives. We hope this article will be helpful for designing and constructing MECSens with outstanding activity for electrochemical analysis.
MXene是一类新型二维纳米材料，具有出色的导电性、可调控结构、生物相容性和大表面积。得益于这些独特的物理化学性质，MXene已被用于构建性能优异的电化学传感器（MECSens）。特别是，MXene丰富的表面端基有助于极大地提高MECSens的分析灵敏度和选择性。近年来，MECSens已广泛应用于包括临床诊断、传染病监测和食品安全在内的许多领域。然而，并非所有的MXene材料都适合用于构建电化学传感器。在本文中，我们对迄今已开发的不同MECSens进行了综述。我们首先简要总结了MECSens的制备和表征。随后，对MECSens的电化学性能、检测策略和应用场景进行了分类并简要讨论。文章最后给出了简短的结论和未来展望。我们希望本文将有助于设计和构建具有出色电化学分析活性的MECSens。
