Outline of Final Research Achievements

In this experiment, we succeeded in the synthesis of CdS, ZnS semiconductor nano-particle (NP)s and Au NPs in the apoferritin cavity with high efficiency. The CdS and ZnS NPs showed the strong red or blue luminescences better than that of some previous reports. We also succeeded in the construction and selection of new Au binding peptide for our search and repair system for a metal defect part on the electric devices. This Au binding peptide could strong bind to the Au electrode of QCM and it showed the high affinity to Au better than that of previous reports . We constructed a Au-binding Bio-NPs by using the ferritin including Au NPs and the Au-binding peptides. The Au-binding Bio-NPs could bind densely to the Au artificial particles with assistance of light irradiation. These results show that the Au-binding bio-NPs can be used to search and repair of a damaged point on Au wiring or electrode of electric devices.
