The incident wavelength, angle and polarization were also proven to greatly affect the performance of an SERS substrate. Previously, Chaney et

Such a SERS substrate is expected to be reusable due to the embedded nanostructures. TRIDYN [20][21], a binary-collision Monte

• the first layer next to the silver nanoparticles undergo the most efficient signal amplification. The simplest approach for quantitative investigations may be to carry out SERS measurements of solutions only in such concentration ranges, in which all binding sites of the SERS substrate are saturated

In both cases the molecules can select favoured binding sites to adsorb to the metal particles. In case of adenine these are the four nitrogen

• thickness 6 nm), the printed patterns could not be detected and localized by confocal RS. Either no Raman signals at all or homogeneous signals from all over the substrate were detected (data not shown). Due to the strong but inhomogeneous enhancement by single sites on a typical SERS substrate, it is most

• likely that a very small fraction of molecules diffusing on the Ag surface during production of the samples dominated the spectra, preventing a localization of the molecules. Another possible explanation is that the roughness of the SERS substrate interfered with the patterning process used (compare
