| Outline of Final Research Achievements |
By using the original self-organized precipitation (SORP) method, core-shell particles comprising of polystyrene core and amino-terminated polybutadiene shell have been prepared. Since obtained particles have positive surface charges, composite particles having gold nanoparticle clusters were successfully prepared by mixing negatively charged gold nanoparticle dispersions with core-shell particles. These particles show strong surface enhanced Raman scattering signals by irradiation of near infrared light excitation. Furthermore, magnetic responsive composite particles were also prepared by introducing magnetic nanoparticles into the composite particles.
