| Outline of Final Research Achievements |
Preparation of metal nanoparticle was studied using DNA as a template, and following results were obtained. In a DNA-hydrogel medium, the smallest gold particles of 2.8 ± 1 nm (diameter) ever reported were prepared. A gold small-size coil (100 nm o.d. and 37 nm i.d.) and a small vesicle with a membrane including DNA and gold or silver nanoparticles were prepared. Metal nanoparticles of single metal or complexed metal (alloy or core-shell type), the size of which was smaller than 5 nm, were prepared in a DNA hydrogel matrix. The DNA-hydrogel and metal nanoparticle complex could be used as a catalyst for the conversion of an aromatic nitro compound to an aromatic amine.
