Research progress in electrochemical sensors based on MXene

MXene is a two-dimensional (2D) layered material composed of early transition metal carbides, nitrides and carbonitride. Due to MXene's unique layered morphology, high electrical conductivity, high specific surface area, excellent hydrophilicity and good thermal stability, it has broad application prospect in the fields of physics, materials, chemistry and nanotechnology. It can also be used in a variety of scientific fields such as catalysis, energy storage and sensors. This paper mainly reviews the research progress in electrochemical sensors based on MXene. Firstly, the principle, composition, electrode surface modification of electrochemical sensors and the preparation methods of MXene were introduced. Then, the research progress of MXene in electrochemical enzyme sensors, electrochemical non-enzyme sensors, electrochemical immunosensors, electrochemical aptamer sensors and electrochemical molecularly imprinted sensors were reviewed. Finally, the industrialization and commercialization of MXene electrochemical sensing field, and the challenges of the development of new types of MXene were pointed out. The applications of MXene in various analytes and more potential fields were also prospected.
