Indirect NanoPlasmonic Sensing (INPS) is a robust, low cost, highly sensitive and fast method for recording processes in/on thin films and nanostructured materials. Metallic and non-metallic systems can be studied in liquid or gas (UHV to high pressure) environments. INPS utilizes the optical signal from state-of-the-art nanofabricated sensor chips decorated with plasmonic (LSPR) gold nanodisks, which act as nanoscale optical antennas and detect events in their proximity, onto which the nanomaterial to be studied is deposited (see figure). INPS case studies including nanoparticle catalyst sintering[1], catalytic activity[2], NOx storage and release in/from barium compounds[3], hydrogen storage in nanoscale systems[2,4] and molecular diffusion through porous layers are presented.
