ABSTRACT
This chapter presents the theoretical background of Surface plasmon resonance (SPR) method from the point of view of its application primarily for sensing and related fields and results of several relevant theoretical studies. It describes principal aspects of the SPR phenomenon in thin noble metal films and its applications. These include studies on three dimensional quantification of molecular covers using SPR and influence of the shape of the particles covering the metal surface on the dispersion relations of surface plasmons. The chapter includes theoretical background of the localized surface plasmon resonance (LSPR) phenomenon and presents results of studies related to the LSPR sensor sensitivity optimization. These include investigations of LSPR response depending on the geometrical parameters of the sensitive element, comparative analysis of different LSPR response measurement modes, and LSPR response analysis for light-absorbing molecular coatings.
