| Outline of Final Research Achievements |
The purpose of this project was to develop the analytical method for multi-component identification of molecules based on surface-enhanced Raman spectroscopy using a gold nanoparticle dimer with single molecule sensitivity. Due to the Raman enhancing hotspot with 1 nm nanogap in the single dimer, for the first time, the single oligomer detection and analysis was demonstrated. The dimer identified the several bases and backbone components of the single DNA oligomer. The dynamics of the single oligomer could be analyzed. The oligomer was trapped and stayed at the nanogap hotspot, and fluctuated with rotation.
