- Surface plasmon resonances that occur in nanoscale noble metal films and particles are extremely sensitive to the local dielectric environment. As a result, both the surface plasmon resonance (SPR) and the localized surface plasmon resonance (LSPR) have attracted a great deal of interest for diverse biological and chemical sensing applications. One avenue to exploiting the remarkable optical properties of nanoscale metals is to make use of their intrinsic capacity for miniaturization, in combination with the powerful manufacturing capabilities that have been developed in the microelectronics and optical telecommunications industries. In this paper we firstly explore the potential for an SPR moisture sensor based on a gold-on-silicon structure. This configuration is shown to be highly sensitive to the dynamics of surface droplet formation. Secondly, we describe efforts to use the LSPR to generate surface enhanced Raman scattering on the tip of an optical fiber. This requires the preparation of well-defined and stable nanoscale features.
