conventional technology is gradually reaching its limits in terms of further enhancement of sensor performance. Hence, tremendous efforts have been taken to explore the applicability of MXenes in various sensor technologies, including chemical, biological, mechanical, and optical sensors. The large specific surface area, high electrical conductivity, [1,2] and water dispersibility of MXenes, among their various excellent properties, constitute essential characteristics of a sensor material. Particularly, the 2D structure of MXene, which is conducive to functionalization using various terminal groups, provides a large number of active surface sites. These sites can serve as a highly responsive sensory platform for various external stimuli. Furthermore, the high electrical conductivity of MXenes is desirable for achieving low noise in sensory responses. Therefore, these characteristics demonstrate MXenes as a highly promising alternative sensor material for achieving high sensitivity, exceptionally low limit of detection (LOD), and minimum detectable amount of analytes in various sensor applications. Finally, the water dispersibility of MXenes facilitates environment-friendly fabrication and modification treatments; thus, they are further advantageous in processing.Because the fundamental properties of MXenes satisfy the requirements for an alternative sensor material, MXenebased sensor technology has been rapidly evolving over the last few years. The field of MXene-based sensors is facing conventional challenging problems as hurdles to commercialization: achieving reliably high performance, high stability, multifunctionality, and realizing homogeneous and reproducible scale-up processing (Figure 1a) of MXene-based sensors. Several recent studies on MXene-based sensors were aimed at establishing various structural and electrical approaches to utilize the excellent properties of MXene, thus boosting the sensor performance. For example, the macrostructuring of MXenes can significantly increase the sensitivity and lower the LOD of the resultant fabricated sensor. [3,4] Furthermore, the functionalization of MXene surfaces can impart useful properties of the secondary component to the MXene-based sensor to obtain higher performance than that of pristine MXenebased sensors. [5] These approaches have been highly effective and reliable, and thus significantly accelerated the progress of MXene-based sensor research. Figure 1b shows the network of co-occurring keywords in 2375 MXene-based research papers published since the discovery of MXenes in 2011. In an attempt to introduce new low-cost, high-performance, and Various fields of study consider MXene a revolutionary 2D material. Particularly in the field of sensors, the metal-like high electrical conductivity and large surface area of MXenes are desirable characteristics as an alternative sensor material that can transcend the boundaries of existing sensor technology. This critical review provides a comprehensive overview of recent advances in MXene-based sensor technology...

MXenes are a family of two-dimensional multifunctional materials in a rapid development phase since their discovery in 2011. MXenes possess excellent features like high conductivity and surface area, improved mechanical properties, hydrophilicity, and ability to tune the surface properties with modifying functional groups. These features make MXenes suitable candidates for a wide range of applications, including biomedical and energy storage. This review is focused on various types of MXenes which are recently reported for sensor applications. The current scenario regarding fabrication and properties of MXenes are initially described, followed by a discussion of their applications as piezoresistive and biochemical sensors. This involves mechanical strain detection and detection of biomolecules, biomarkers, and drug molecules relevant to biomedical applications. Finally, the future perspectives are briefly discussed, which will help the researchers identify the limitations for the current scenario and develop new strategies that focus on developing novel, efficient and sensitive MXene based sensors.
