Abstract
The present disclosure relates to a gas sensor including a first layer and a second layer superimposed on each other along an interface between the two layers. The first layer includes an array of nanoparticles along the interface, the nanoparticles provided so as to allow, upon illumination with electromagnetic radiation, long range diffractive coupling of surface plasmon resonances resulting in a surface lattice resonance condition. The second layer includes a material that, when exposed to at least one predetermined gas, detectably affects the surface lattice resonance condition. The material of the second layer preferably has a porosity of at least 10%.
