• thirdly with the employed substrate. Moreover, we obtained strongly enhanced Raman spectra of an adenine (sub-)monolayer on gold Fischer patterns on glass. We thus showed that gold Fischer patterns are promising surface-enhanced Raman scattering (SERS) substrates. Keywords: Fischer pattern; higher order

• laser modes; localised surface plasmons; near field; surface-enhanced Raman scattering; Introduction The interaction of light and matter is especially intriguing in those cases where the size of the matter particle is comparable to or smaller than the wavelength of the light. When illuminating metallic

• arrays are long known to yield particle-enhanced Raman spectra [13][14][15]. Hence, there have also been several works [16][17][18] using the near field of Fischer patterns for surface-enhanced Raman scattering (SERS [19][20]). However, to our knowledge, no investigations of Fischer patterns by higher

For a fast, specific, and sensitive detection of molecules at low concentration, EGNP were applied for qualitative as well as quantitative SERS measurements
