SERS sensing of cancer biomarkers

In this work, we establish the use a SERS biosensor based on gold fishnet as a label-free analytical technique for direct detection of glycerophosphoinositol (GroPIns). Here we demonstrate that with our approach we can quantitatively determine low concentration of GroPIns (200 nM) in multicomponent mixtures, with a high accuracy (up to 6%). © 2014 AEIT.
