Detection of Individual Vapors and Their Mixtures Using a Selectivity‐Tunable Three‐Dimensional Network of Plasmonic Nanoparticles

Sensor selectivity: Selective detection of individual vapors and their mixtures is achieved by using a single three-dimensional networked film of organothiol-functionalized plasmonic nanoparticles (see picture). This approach gives a new perspective for sensing, where tunable selectivity is achieved within a single sensing film, rather than from an array of separate conventional sensors.
