Graphene-based sensors offer exceptional potential for the advancement of electronic nose (e-nose) and electronic tongue (e-tongue) technologies. Their high surface area, excellent electrical conductivity, and tunable surface chemistry enable the detection of a wide range of analytes with remarkable sensitivity and speed. This presentation explores the recent progress in utilizing graphene and its derivatives, such as MoS 2 , for the fabrication of e-nose and e-tongue sensor arrays. These devices aim to mimic the human olfactory and gustatory systems, providing rapid and accurate analysis of volatile organic compounds (VOCs) and taste profiles. We will discuss the various functionalization strategies employed to enhance selectivity, and also discuss the application of these devices in areas such as: food quality monitoring, environmental analysis, and medical diagnostics. Furthermore, we will highlight the work of our group and their specific contributions to this emerging fields.
