Fluid Diagnosis – with SERS

Ever-increasing knowledge of the molecular mechanisms underlying cancer are supercharging the development of improved diagnostic tools. Capitalizing on this knowledge, surface-enhanced Raman scattering (SERS) has demonstrated utility in the liquid biopsy of gastrointestinal tumors. “Replacing endoscopy with a non-invasive liquid strategy could tremendously improve gastrointestinal tumor diagnosis by sparing patients this unpleasant procedure,” says Vlad Moisiou – a spectroscopist investigating the approach.
