| Outline of Final Research Achievements |
Surface-enhanced Raman scattering spectroscopy uses metallic nanostructures, which amplifies Raman scattering signal from the molecule existing near the metal surface. Since it can identify molecular species of the sample at high sensitivity, and further provides information of the molecular structure and surrounding environment, it is expected to be a promising analytical method for various research fields. However, the range of its application has been limited, since the precise control of the degree of signal amplification is often challenging. In this research, digital counting was considered to use for the measure of the quantification of SERS signal, instead of the SERS signal intensity. By using it, improvement of the sensitivity of SERS measurement and quantitative analytical capability was examined.
