Abstract
The detection of organic traces by surface-enhanced Raman scattering (SERS) requires rough metallic substrates with structures in the nanometer range. Regular metallic structures generated by electron-beam lithography are bet ter reproducible than electrochemical roughened surfaces, island films or f ilms over deposited particles. The lithography also allows optimisation of the dimensions of these structures. The SERS enhancement of optimised perio dic structures was found to be at least one order of magnitude larger than that of island films. (C) 1998 Elsevier Science S.A. All fights reserved.
