Detection of the specific Anthrax biomarker-protective antigen (PA) by Surface-enhanced Raman spectroscopy (SERS) (CAT#: STEM-ST-0043-WXH)

Surface-enhanced Raman spectroscopy or surface-enhanced Raman scattering (SERS) is a surface-sensitive technique that enhances Raman scattering by molecules adsorbed on rough metal surfaces or by nanostructures such as plasmonic-magnetic silica nanotubes. The enhancement factor can be as much as 1010 to 1011, which means the technique may detect single molecules.
