“…The two primary categories for producing MXenes from MAX or non-MAX precursors and i-MAX precursors are considered to be "topdown" and "bottom-up" techniques. [15][16][17] The "top-down" approach allows the MAX phase to be divided/exfoliated into layers, which is the main distinction between these two methods. In contrast, the deposition of materials from base to surface will be achieved in the "bottom-up" approach.…”

Two-dimensional materials have garnered significant attention in recent years due to their unique physical and chemical properties, making them promising candidates for advanced electronic technologies. Graphene, in particular, has shown extraordinary qualities with the potential for highly efficient and durable electronic devices, overcoming technological limitations associated with downsizing. However, the absence of a band gap in graphene's structure has led researchers to explore alternative materials for transistor applications. MXene and its derivatives were developed in response to this shift in emphasis as potential solutions for constructing electronic systems. Simple changes in surface termination, the introduction of metal ions, careful management of etching duration, and suitable surface functionalization can improve the characteristics of MXene, which are similar to those of graphene. These modifications result in the desired band structure, enabling advanced applications. This review provides an overview of the most recent advancements in MXene-based materials design, highlighting challenges and future prospects, specifically focusing on the efficient design of field-effect transistor (FET) gas sensing devices. The underlying goal is to familiarize the readers with the MXene in FET-based sensing applications and summarize recent development in this field to transition to next-generation electronic devices.

“…MXenes are 2D transitional metal carbides/nitrides/carbonitrides, obtained by the selective etching of the so-called MAX phases ( Figure 1 ). MAX phases are conductive 2D layers of transition metal carbides/nitrides interconnected by the ‘element A’ (Group 13–16) through strong ionic, metallic, and covalent bonds [ 14 , 15 ]. In chemical exfoliation, method hydrofluoric acid (HF) or a mixture of lithium fluoride and hydrochloric acid (HCl) are used, while the electrochemical selective exfoliation procedure is assumed as a fluoride-free etching procedure [ 14 ].…”

Two-dimensional (2D) nanomaterials (e.g., graphene) have attracted growing attention in the (bio)sensing area and, in particular, for biomedical applications because of their unique mechanical and physicochemical properties, such as their high thermal and electrical conductivity, biocompatibility, and large surface area. Graphene (G) and its derivatives represent the most common 2D nanomaterials applied to electrochemical (bio)sensors for healthcare applications. This review will pay particular attention to other 2D nanomaterials, such as transition metal dichalcogenides (TMDs), metal–organic frameworks (MOFs), covalent organic frameworks (COFs), and MXenes, applied to the electrochemical biomedical (bio)sensing area, considering the literature of the last five years (2018–2022). An overview of 2D nanostructures focusing on the synthetic approach, the integration with electrodic materials, including other nanomaterials, and with different biorecognition elements such as antibodies, nucleic acids, enzymes, and aptamers, will be provided. Next, significant examples of applications in the clinical field will be reported and discussed together with the role of nanomaterials, the type of (bio)sensor, and the adopted electrochemical technique. Finally, challenges related to future developments of these nanomaterials to design portable sensing systems will be shortly discussed.

The flexibility and sensitivity of traditional sensors is hard to achieve unless wearable technology develops. Flexible piezoresistive sensor (FPS) is one of the solutions in the nondestructive health monitoring of living body. In the application of sensing devices for physiological or biochemical signals, fast feedback speed and accurate signal feedback are essential requirements for obtaining sensitive response signals. Additionally, the development of FPS has promoted the research of conductive materials that could be used in wearable devices. However, improving the performance of functional materials is an important way of effort for researchers. Recently, MXene as a new kind of 2D materials and their composites have made a tremendous impact in the field of sensors for wearable health sensors. Numerous conductive materials based 2D MXene could expedite their practical application in FPS by overcoming the present limitations of FPS such as poor responsivity, signal accuracy, and the narrower corresponding range. There has been plenty of breakthrough in the MXene-based FPS in the past several years. The main purpose of this paper is reviewing the recent development of MXene-based FPS and providing an outlook on the future development of it.
