摘要： 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%.

摘要： An analyte sensing device is disclosed. In one aspect, the device includes at least one sensing module on a substrate. The sensing module has at least one nanowire including a bottom, an intermediate part and a top, the bottom being closer to the substrate than the top. The module has a surrounding electrode surrounding the bottom and at least part of the intermediate part of each nanowire in height direction and being electrically isolated from the nanowire. There is a gap between each nanowire and the corresponding surrounding electrode allowing penetration of an analyte to be detected between the nanowire and the surrounding electrode. A measurement circuitry is electrically connected to each nanowire and the surrounding electrode for detecting a change in an electrical property as a result of the penetration of the analyte into the gap.
