| Outline of Final Research Achievements |
We have tried to clarify a principle to convert the characteristics of collective modes of electronic excited states in a nanoparticle-assembled system into "macroscopic flow" via photothermal effect, and aimed at the application to nano-bioscience. When each dispersion liquid of diluted egg white or egg yolk was added into the dispersion liquid of spherical-shell type metallic nanoparticle-assembled structures, laser was irradiated with each mixture and included proteins were detected via thermal solidification due to enhanced photothermal effect arising from collective effect of localized surface plasmon therein. Particularly, the required time for bubble generation and thermal solidification was different depending on the component in each sample. Also, we have clarified the condition for the assembling organic nanocapsules including gold nanoparticles into the aimed position in their dispersion liquid by laser irradiation.
