Quantitative surface enhanced resonance Raman scattering (SERRS) requires effective adsorption of the analyte onto the metal surface. A range of dyes incorporating the benzotriazole group has been specifically designed to achieve this and they have proved successful labels for obtaining very sensitive analysis. However, if the spectra were more fully understood, the differences between the Raman spectrum...
The detection of dye labelled DNA by surface enhanced resonance Raman scattering (SERRS) is reported. The dye labels used are commercially available and have not previously been used as SERRS dyes. Detection limits using two excitation frequencies were determined for each label. This expands the range of labels which can be used for surface enhanced resonance Raman scattering with silver nanoparticles.
