Abstract
Raman scattering represents the information of analyte molecules through scattering light with characteristic vibrational wavelength. Since this phenomenon is rarely occurred, biological activities occurring in short time is difficult to observe. Raman scattering can be enhanced with using metal nanoparticles. Molecules existing nearby or adsorbed on the metal nanoparticles make Raman scattering stronger due to the locally enhanced electric field around the metal nanoparticles (surface-enhanced Raman scattering; SERS). SERS enables us to observe biomolecules in short time associated with biological events.
