Outline of Final Research Achievements

GNPs are one of typical functional nanoparticles with unique features contributing to the development of nanoparticle-based technologies in optical, electric, and catalytic applications. One of our works is colorimetric observation of fast reactions related to GNPs, such as GNP syntheses and catalytic reactions by GNPs. GNPs also show the catalytic activities both of oxidations and reductions and, thus, the colorimetric catalytic reactions are useful for evaluation of their activities. We have achieved to monitor the above reactions by a diode-array spectrophotometer. Furthermore, we have found a new technique fabricationg GNP-assembled microtube, in which no energy is need during spontaneous formation of the microtube. These results can contribute to the understanding of GNP catalyst as substitution of functional enzymes and also to the developmento of mixed system of GNPs and enzymes
