Paper Abstract

Surface enhanced resonance Raman scattering (SERRS) provides an increase in sensitivity over Raman scattering of about 1014 and rivals fluorescence in terms of its quantum efficiency. With the use of modern edge and notch filters and CCD cameras, the price and complexity of Raman spectroscopy equipment has decreased rapidly. This means that the potential advantages of SERRS are now much easier to release for use for practical purposes. The technique has specific advantages in terms of sensitivity and coding for use for tagging.
