Surface Enhanced Raman Spectroscopy
Surface enhanced Raman spectroscopy is a surface treatment technology that enhances the Raman
scattering efficiency in which molecules are absorbed on a nanostructure surface such as plasmonic-magnetic
silica nanotubes or Au/Ag based nano-treated surface. The enhancement factor can be as much as 103-1012,
which means the limit of detection may be down to single molecules.
SERS is a “hot” technology nowadays since it can be used for cancer detection and screening in biomedical applications, low concentration monitoring of water quality control in environment pollution protection, target component discovery of additive or contaminants in the food industry and forensic science as well to detect illegal drugs contained in suspicious samples.
