A 2D nanosheet-based photonic nose for vapor identification is presented. A HSbP₂O₈ nanosheet thin-film sensor with resistive readout is developed for the tracking of trace amounts of water, and a photonic HSbP₂O₈/TiO₂ multilayer structure is effective at optically distinguishing between chemically similar solvent vapors through analyte-specific host–guest interactions.
