The recent discovery of the extraordinary optical transmission (EOT) effect in periodic nanohole arrays in a metal film shows promise for building a new generation of biosensors utilizing this unique phenomenon in nano-structured metallic substrates. These sub-wavelength holes act as miniaturized optical antenna to capture incident photons and convert them to energetic surface plasmon waves, which can be used as a sensitive probe for biomolecular interactions on the surface or as new electrodes for enhancing the power conversion efficiency of photovoltaic cells. In this presentation, the application of the EOT effect for real-time label-free SPR biosensing will be demonstrated, followed by surface enhanced Raman scattering (SERS) applications and plasmonic photovoltaic cells.
