“…In another approach, self‐assembly of organic molecular‐functionalized graphene films has been utilized to construct gas/vapor detectors. Ji et al reported a VOC sensor fabricated by layer‐by‐layer assembly of graphene–ionic liquids (G‐ILs) on a quartz crystal microbalance. The decrease in frequency shifts, caused by gas adsorption, for single adsorption steps corresponds to the adsorption of the single G‐IL composite layer.…”

Development of next-generation sensor devices is gaining tremendous attention in both academia and industry because of their broad applications in manufacturing processes, food and environment control, medicine, disease diagnostics, security and defense, aerospace, and so forth. Current challenges include the development of low-cost, ultrahigh, and user-friendly sensors, which have high selectivity, fast response and recovery times, and small dimensions. The critical demands of these new sensors are typically associated with advanced nanoscale sensing materials. Among them, graphene and its derivatives have demonstrated the ideal properties to overcome these challenges and have merged as one of the most popular sensing platforms for diverse applications. A broad range of graphene assemblies with different architectures, morphologies, and scales (from nano-, micro-, to macrosize) have been explored in recent years for designing new high-performing sensing devices. Herein, this study presents and discusses recent advances in synthesis strategies of assembled graphene-based superstructures of 1D, 2D, and 3D macroscopic shapes in the forms of fibers, thin films, and foams/aerogels. The fabricated state-of-the-art applications of these materials in gas and vapor, biomedical, piezoresistive strain and pressure, heavy metal ion, and temperature sensors are also systematically reviewed and discussed, and their sensing performance is compared.

“…Several recent studies have reported that the incorporation of nanocrystals/nanoparticles in graphene-based gas sensors could improve sensor performance in terms of the sensitivity/detection limit, response time, or recovery time161718. In addition, several other groups have demonstrated that reduced graphene oxide (rGO) can act as a gas/vapour sensor with promising results111219202122. However, at present there have been no reports demonstrating selectivity using graphene and rGO in gas sensors.…”

New hydrophilic 2D graphene oxide (GO) nanosheets with various oxygen functional groups were employed to maintain high sensitivity in highly unfavorable environments (extremely high humidity, strong acidic or basic). Novel one-headed polymer optical fiber sensor arrays using hydrophilic GO and hydrophobic reduced graphene oxide (rGO) were carefully designed, leading to the selective sensing of volatile organic gases for the first time. The two physically different surfaces of GO and rGO could provide the sensing ability to distinguish between tetrahydrofuran (THF) and dichloromethane (MC), respectively, which is the most challenging issue in the area of gas sensors. The eco-friendly physical properties of GO allowed for faster sensing and higher sensitivity when compared to previous results for rGO even under extreme environments of over 90% humidity, making it the best choice for an environmentally friendly gas sensor.

“…Recently, graphene has attracted much attention due to its unique single atom-layer structure, which contributes to its wide applications [26] in nanoelectronics, sensing devices, energy storage, and even tissue engineering. For example, graphene has proven to be a promising biocompatible scaffold that could accelerate the specific differentiation of human mesenchymal stem cells (hMSCs) into bone cells.…”
