Emergence and Recent Advances in MXenes for Diverse Sensing Applications

Many scientific fields regard MXene as a ground-breaking 2D material. The metal-like great electrical conductivity and high surface area of MXenes are attractive properties as an innovative sensor material that can go beyond the limitations of current sensor technology. This is especially true in the field of sensors and transducers as a whole. The thorough analysis offers a road map for commercializing MXene-based sensors as well as an extensive overview of current developments in sensor technology. Pressure and strain, electrochemical, biological, gas, capacitive, and photoluminescent sensors are the few broad categories into which the current sensors based on MXenes and their composites are meticulously organized. The performance of each class is improved using exemplary structural, compositional, and production strategies, which are presented and discussed in detail. Finally, obstacles that prevent MXene-based sensors from being commercialized are examined, and potential directions to realize MXene-based sensors that can be viable and marketable are looked upon. This chapter thus unequivocally offers a comprehensive analysis of past and present MXene-based sensor technologies as well as promising foresight for the next generation of multimodal, low-cost, high-performance sensors for electronic applications.
