TL;DR: Comparing simultaneously graphene and sensors prepared via different routes provides the first experimental evidence of the role played by the graphene level of defectiveness in the interaction with analytes, and can pave the path for tailoring the sensor behavior as a function of graphene morphology.

TL;DR: An extensive review of the low-cost particulate matter sensors currently available on the market, their electronic characteristics, and their applications in published literature and from specific tests shows that most of the reviewed LCPMS can accurately monitor PM changes in the environment and exhibit good performances with accuracy that, in some conditions, can reach R2 values up to 0.99.

TL;DR: This paper presents a review of the current research activities in the field of gas nanosensors and focuses most attention on carbon nanotubes, silicon and metal oxide nanoparticles and metal nanowires.

TL;DR: In this paper, the authors investigated the effect of graphene decoration with metal nanoparticles, namely Ag and Pd, starting from pristine graphene (GR) and found that Ag nanoparticles enhanced graphene response towards hydrogen, nitrogen dioxide and ammonia detection.

TL;DR: In this paper, a new type of filler, carbon nanoparticles obtained by flame synthesis, was used as a filler for composite polymer vapor sensors, and the characteristics of the sensors responses to volatile organic compounds were related to filler types.
