“…To date, 2D FETs have been demonstrated with great promise in proof-of-concept applications such as mechanical, optical, gas, ion, protein, bioelectric, and other sensors, as summarized in Figure . Before their commercialization from the lab to market, there are at least three challenges that should be addressed: (i) how to further improve the sensor performance at single-device level; (i) how to integrate prototypes with standard card cages; (iii) how to optimize the function, reliability, cost, and user interface for commercial products. , To meet these challenges, considerable efforts have been made in integrating industrial technologies with the development of 2D FET sensors, which include fundamental outcomes at single-device level, ,− techniques for integration and standardization, − and attempts for preparing commercial prototypes. ,, …”

The evolutionary success in information technology has been sustained by the rapid growth of sensor technology. Recently, advances in sensor technology have promoted the ambitious requirement to build intelligent systems that can be controlled by external stimuli along with independent operation, adaptivity, and low energy expenditure. Among various sensing techniques, field-effect transistors (FETs) with channels made of two-dimensional (2D) materials attract increasing attention for advantages such as label-free detection, fast response, easy operation, and capability of integration. With atomic thickness, 2D materials restrict the carrier flow within the material surface and expose it directly to the external environment, leading to efficient signal acquisition and conversion. This review summarizes the latest advances of 2D-materials-based FET (2D FET) sensors in a comprehensive manner that contains the material, operating principles, fabrication technologies, proof-of-concept applications, and prototypes. First, a brief description of the background and fundamentals is provided. The subsequent contents summarize physical, chemical, and biological 2D FET sensors and their applications. Then, we highlight the challenges of their commercialization and discuss corresponding solution techniques. The following section presents a systematic survey of recent progress in developing commercial prototypes. Lastly, we summarize the long-standing efforts and prospective future development of 2D FET-based sensing systems toward commercialization.
