Abstract

Materials in thin-film structures for optical sensing applications must have multiple features: (i) enhancing the optical signal providing high optical sensitivity for the measurement of the interface processes, (ii) having appropriate chemical properties for supporting the adsorption of the molecules to be detected, (iii) having stability and selectivity. Development of materials that meet all these requirements is an ever lasting process with a lot of opportunities. In this work we propose porous silicon nanoparticles for the detection of biomolecules in plasmonic and Bragg multilayer enhanced Kretschmann-Raether ellipsometry configurations.
