| Outline of Final Research Achievements |
It is expected that two-dimensional metal nanoparticle arrays exhibit new functions that are derived from interparticle interaction between the particles. We found that gold nanoparticle array shows characteristic reflection spectra and that can be used as a more sophisticated localized surface plasmon resonance (LSPR) sensor than the conventional one. We also found a facile method to deposit metal nanoparticles on ITO, titanium dioxide, and other electrodes. On the basis of the method, various electrodes modified with metal nanoparticles were fabricated and applied to studies on plasmon-induced charge separation (PICS) by the use of gold-silver alloy nanoparticles, photo-induced dealloying of the alloy nanoparticles, oxidation potential of PICS, and potential-scanning LSPR sensors.
