SERS for Label-Free Biosensing

Author(s):

Cicely Rathmell,Ocean Optics

Surface enhanced Raman spectroscopy (SERS) has expanded the applications of Raman spectroscopy to include trace analysis of materials such as explosives residues, evidence at crime scenes, chemical warfare agents and pesticides. As a label-free technique, SERS is also well suited to biosensing, from blood glucose to diagnosis of diseases like cancer, Alzheimer’s and Parkinson’s.
