TL;DR: A high-performance gas sensor constructed using atomic-layered MoS2 synthesised by chemical vapour deposition (CVD) was developed and the in situ PL characterisation of the changes in the peaks corresponding to charged trions and neutral excitons via gas adsorption processes was used to elucidate the mechanisms of charge transfer between theMoS2 and the gas molecules.

TL;DR: This novel sensing structure based on a 2D heterostructured device on a flexible substrate promises to provide a simple route to an essential sensing platform for wearable electronics.

TL;DR: The fabrication of a flexible transparent electrode with superior mechanical, electrical and optical properties is demonstrated by embedding a AgNW film into a transparent polymer matrix and can produce electrodes with an ultrasmooth and extremely deformable transparent electrode that have sheet resistance and transmittance comparable to those of an ITO electrode.

TL;DR: In this paper, the role of metal nanoparticles (NPs) on graphene-based devices was investigated in terms of gas-sensing characteristics of NO2 and NH3, and flexible gas sensing was also realized for future applications.

TL;DR: The SERS-based imaging aptasensor platform proposed in this work overcomes the issues inherent in conventional approaches (the time-consuming and labor-intensiveness of RT-PCR and low sensitivity and quantitative analysis limits of lateral flow assay kits).
