Abstract: A sensor device is provided for determining the presence and/or amount of at least one component in a fluid. The sensor device comprises at least one sensor unit, the at least one sensor unit comprising at least one elongated nanostructure and a dielectric material surrounding the at least one elongated nanostructure. The dielectric material is such that it is selectively permeable for one of the at least one component and is capable of sensing the component permeated through the dielectric material. The sensor device according to preferred embodiments shows good sensitivity and good mechanical strength. The present invention furthermore provides a method for manufacturing such a sensor device and a method for determining the presence and/or amount of at least one component in a fluid using such a sensor device.

Abstract: The present invention relates to a gas sensing device comprising a nanoparticle layer (1) and a quantum dot layer (3) separated from each other by a gas absorption layer (2) which has a thickness which changes upon absorption of a gas. The nanoparticle layer (1) is provided for generating a surface plasmon resonance within a plasmon resonance frequency range upon illumination with light within a light frequency range; the quantum dot layer (3) has an absorption spectrum overlapping with said plasmon resonance frequency range of said nanoparticle layer (1) and shows photoluminescence in a photoluminescence emission frequency range upon absorption of energy within its absorption spectrum. The present invention further relates to a method for fabricating such a gas sensing device and to a method of using such a gas sensing device.

Abstract: 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.
