    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: A metal nanoantenna for use in a biosensing device is disclosed. The metal nanoantenna is arranged to exhibit at least two particle plasmon resonances or surface plasmon resonances (SPRs). The nanoantenna is for use in a sensor and allows detection at low concentration of biological components. In one aspect, the nanoantenna can have an asymmetric structural configuration and spectrally separated resonances. In one aspect, there is a location in its structure providing local electromagnetic field enhancement at all of the SPRs. The metal nanoantenna can be used for background free measuring of a quantity of a biological component.
