Description
Summary:Gas Sensors In article number 2105199, Yeon Sik Jung and co‐workers achieve highly selective, quantitative, and multiplex detection of mixed trace level aromatic compound gases through synergistically integrated multimodal sensing. The design of the 3D cross‐point multifunctional nanoarchitecture (3D‐CMA) significantly enhances both chemoresistive sensing and surface‐enhanced Raman spectroscopy simultaneously. 3D‐CMA multimodal sensors accurately identify the composition and concentrations of mixed gases with very similar molecular structures.
