Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

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.
