Surface-enhanced Raman scattering (SERS) is a valuable analytical phenomenon that allows for highly sensitive structural detection of low concentration analytes in the presence of nanometre-sized metallic particles. The SERS enhancement depends strongly on the nanoparticle size, shape and spatial distribution. As a result, recent research has been focused on the development of SERS substrates [1] using e-beam and nanolithography methods, focused ion beam milling and template directed synthesis.
