“…Graphene can also be used as a sensing material in ion selective field effect transistors (ISFET) to measure the content of low-concentration metal ions. Alves et al [97] . A graphene-based metal ion (Na, Co, Al, Cu) sensor is proposed, in which graphene is functionalized by L-phenylalanine, and L-phenylalanine is attracted and combined with metal ions.…”

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.

“…in aqueous solutions is of importance for human health and environmental safety. 200 Numerous groups have developed GFET devices and implemented them for the sensitive detection of a wide range of metal ions including Hg 2+ , 201 Pb 2+ , 202 Cu 2+ , 203 Fe 3+ , 204 K + , 205 Na+, 206 Co 2+ , 206 etc. As pristine graphene does not adsorb heavy metal ions selectively in most cases, the surface of the graphene channel in GFETs is functionalized with different functional groups to enhance their binding affinity and selectivity to heavy metal ions.…”
