This chapter focuses on the characterization of polymer films hy the spectroscopy of (leaky) surface plasmon (SP) and dielectric waveguide modes. The fundamentals of optics that are essential for the understanding and implementation of these techniques are presented (Section 2.26.2). Models that can he employed for the evaluation of optical response in order to assess the information on phenomena including adhesion of polymers on a surface, swelling of polymer films in solvents, and diffusion and interaction of biomolecules in polymers are discussed (Section 2.26.3). The performance characteristics of presented methods are illustrated with a focus on highly swollen polymer networks (cross-linked hydrogels and bmshes) tethered on gold surfaces (Section 2.26.4).
