Abstract:

Biomolecule-assisted surface-enhanced Raman scattering(SERS) sensing is a technique using biological molecules as sensitive components or detected objects, which is one of the most important tools in the studies of biological molecules. SERS biosensing is widely used in environmental monitoring, food-safety, clinical testing, disease diagnosis, and many other areas. This paper summarizes the progresses on the application of SERS technique in the fields of the analysis and diagnosis of cancer. The contents mainly consist of three parts: (1) SERS biosensing technology based the new coupling mechanisms, involving SPR-coupling, waveguide-coupling and LSPR-PSPR coenhancement; (2) preparation and application of highly sensitive SERS chips; and (3) new SERS technology for investigating cancer cells and bio tissues.

Key words: Surface-enhanced Raman scattering, Biosensor, SERS chip, Immunoassay, Cancer
