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.
