Gas sensors have been object of increasing attention by the scientific community in recent years. For the development of the sensing element, two major trends seem to have appeared. On one hand, the possibility of creating complex structures at the nanoscale level has given rise to ever more sensitive sensors based on metal oxides and metal–polymer combinations. On the other hand, gas biosensors have started to be developed, thanks to their intrinsic ability to be selective for the target analyte. In this review, we analyze the recent progress in both areas and underline their strength, current problems, and future perspectives.

Air pollution is becoming an increasingly important global issue. Toxic gases such as ammonia, nitrogen dioxide, and volatile organic compounds (VOCs) like phenol are very common air pollutants. To date, various sensing methods have been proposed to detect these toxic gases. Researchers are trying their best to build sensors with the lowest detection limit, the highest sensitivity, and the best selectivity. As a 2D material, graphene is very sensitive to many gases and so can be used for gas sensors. Recent studies have shown that graphene with a 3D structure can increase the gas sensitivity of the sensors. The limit of detection (LOD) of the sensors can be upgraded from ppm level to several ppb level. In this review, the recent progress of the gas sensors based on 3D graphene frameworks in the detection of harmful gases is summarized and discussed.

AbstractDiversified regulation of electrons have received much attention to realize a multi-functional transistor, and it is crucial to have a considerable control over the charge carriers in transistors. Ionic gel, as the dielectric material in transistors, facilitates a large capacitance, and high induced-carrier concentrations. This review presents the recent progress in ionic-gated transistors (IGTs) that have good mechanical stability as well as high physical and chemical stability. We first briefly introduce the various applications of IGTs in sensors, neuromorphic transistors, organic transistor circuits, and health detection. Finally, the future perspectives of IGTs are discussed and some possible solutions to the challenges are also proposed.
