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.

Alzheimer's disease (AD) is a neurodegenerative disorder that affects millions of people worldwide. Early screening is crucial to prevent potential damages, and researchers are exploring alternative approaches such as multiplexed assays and emerging technologies such as microfluidics, nanotechnology, and biosensors. Current mainstream and conventional tests for AD biomarkers have limitations due to their insufficient sensitivity, which has led to the development of next-generation biosensing techniques that use nanomaterial-based field-effect transistors (FETs) for high-sensitivity and high-integration label-free biosensing. This review provides an overview of AD biomarkers, the working principle of FET biosensors, recent advances in CNT-based FET biosensors for the detection of AD biomarkers, and their potential for clinical diagnosis. FET biosensors have the potential to revolutionize the clinical detection of AD biomarkers, but there are challenges that need to be addressed for their successful translation into practical applications. In this review, we will provide an overview of the current understanding of AD biomarkers, describe the working principle of FET biosensors, and highlight recent advances in the development of CNT-based FET biosensors for the detection of AD biomarkers, with a particular emphasis on Aβ and tau proteins. We will also discuss the potential of these biosensors for clinical diagnosis and the challenges that need to be addressed for their successful translation into practical applications.

The WHO notes that diabetes can contribute to various health problems, such as blindness, lethargy, kidney failure, strokes, numbness, and heart attacks. Diabetes can be an even worthy- noting problem in developing countries. In many developing countries, there has been significant economic growth over the past decade, but current projections indicate a slowing of this trend. Thus, it is crucial to prevent missed diagnoses and delayed treatment, as these could lead to fatal consequences. Regular glucose monitoring is an indispensable diagnostic tool that allows doctors to identify early symptoms of diabetes and administer timely treatment to avert severe complications. This review provides a peek into the basics of graphene, as well as the very recent advances since 2020 utilizing graphene, GO, rGO, and other novel graphene composite to monitor glucose.
