Sensing is not the only area where SPWs through SPR are involved. One of the first uses was to determine the thickness and relative dielectric constant of metals by employing the Kretschmann configuration. Later on, the excitation of SPWs was involved in microscopy to image low contrast samples like monolayer because of the generated high field intensity, SPWs have been combined with other optical phenomena like Raman scattering to enhance their weak signal (Surface Enhanced Raman Spectroscopy).
