| Outline of Final Research Achievements |
Preparation and surface modification of gold nanoparticles has been studied to develop a plasmonic sensor. A facile 2D self-assembly method was developed for the preparation of gold nanoparticle array on substrates using block copolymer nanotemplates. Well-ordered gold nanoparticle array was applied to a local surface plasmon resonance (LSPR) sensor. We also have developed a novel sensor combined surface plasmon- and fluorescence spectroscopy. The gold nanoparticle array was formed on a SiO2 layer containing fluorescence dyes. The resonant excitation of local surface plasmon resonance provides an enhanced intensity of fluorescence of dyes, which is directly translated to changes of fluorescence intensity measured upon the capture of target analyte at the surface of gold nanoparticles.
