Abstract: A system for label-free detection of a presence of a particle in a fluid comprises: a nanochannel configured to receive the fluid, a light source, a light sensor, arranged to determine an amount of scattered light from a section of the nanochannel. The light being scattered by the section of the nanochannel, the fluid in the section of the nanochannel, and, if present in the section of the nanochannel, the particle. A processing unit arranged to communicate with the light sensor and to determine the presence of the particle in the fluid in the section of the nanochannel based on received data from the light sensor. A method for determining a presence of a particle in a fluid is also disclosed.

Abstract: The present invention relates to a battery (100) comprising an electrode material (102a), an electrolyte material (104), a battery charge sensor (106, 206, 306) comprising a plasmonic sensing element (108, 208, 308) having a sensing volume (110, 210, 310) within the battery (100, 200, 401) and which upon illumination with electromagnetic radiation exhibits a localized surface plasmon resonance condition being dependent on a charge state of the battery (100, 200, 401). A system and a method for determining a charge state of a battery are further provided.

Abstract: The invention concerns an arrangement comprising at least one sensor nanoparticle supporting Localized Surface Plasmon Resonance (LSPR), at least one sensing material and at least one separating layer which separates the at least one sensor nanoparticle from the at least one sensing material. The arrangement allows for indirect sensing studies of change in and on the surface of a sensing material or environment by the sensor nanoparticle. The arrangement may also be used for optical temperature measurements and calorimetry, optical differential scanning calorimetry (DSC), to study hydrogen storage, catalytic reactions or for NOx sensing.

Abstract: The present invention relates to a gas sensor comprising a sensor layer (100) comprising a plasmonic sensor (102) provided so as to allow, upon illumination with electromagnetic radiation a localized surface plasmon resonance condition, a sensing layer (106) comprising a gas permeable material that, when exposed to a gas, modifies the localized surface plasmon resonance condition, a separating layer (104) arranged in between the sensor layer (100) and the sensing layer (106) such that the plasmonic sensor (102) is separated from the sensing layer (106). A gas sensing system and a method for sensing a presence of a gas is further disclosed.
