Paper Abstract
In this Manuscript, we present the fabrication and spectroscopic characterization of a large-area surfaceenhanced
Raman scattering (SERS) substrate, as well as a method for improving femtomole-level trace
detection (109 molecules) using this substrate. Using multiphoton-induced exposure of a commercial
photoresist, we physically limit the available molecular adsorption sites to only the electromagnetic "hot
spots" on the substrate. This process prevents molecules from adsorbing to sites of weak SERS
enhancement, while permitting adsorption to sites of extraordinary SERS enhancement. For a randomly
adsorbed submonolayer of benzenethiol molecules the average Raman scattering cross-section of the
processed sample is 27 times larger than that of an unprocessed SERS substrate.
