This proceeding is a summary of our progress in both fundamental studies of surface enhanced Raman scattering (SERS) active surfaces and the design and characterization of nanostructured SERS-active surfaces. Based on the prior demonstration of single molecule SERS (smSERS)-like behavior from vapor deposited thin silver films, we've focused on these substrates as model systems for fundamental studies of the "blinking" phenomenon. Preliminary studies suggest that Stokes-shifted emission "blinking" is more directly associated with metal nanofeatures and less dependent on the nature of the adsorbate. It is anticipated that the insight provided by these fundamental studies will eventually lead to the rational design of nanostructured surfaces capable of smSERS. Toward that goal, preliminary characterization of the optical properties of nanoaperture arrays in silver suggests that these surfaces may exhibit SERS enhancement greater than that of the overlaying thin silver film.
