New advances in analytic and diagnostic technologies based on Raman spectroscopy

The progress of a method employed in a particular field should be considered for both knowledge and technological advances while equipment grows along with specific challenges. In this context we present our most recent results in using surface enhanced Raman scattering (SERS) as a real time diagnostic means in veterinary oncologic surgery. The in-house built portable Raman spectrometer is based on fibre optics technology and employs visible excitation light. A model for a diagnostic sequence based on principal component analysis is also presented.
