Outline of Final Research Achievements

In order to analyze abnormal-type prion proteins as an index of prion disease with high accuracy, rapid and throughput, we have developed a system of highly sensitive fluorescence correlation spectroscopy using enhancement of electric field in the gap region between metal nano structures. First, we developed the method to efficiently build optical nano antenna structures by connecting gold nano rods synthesized by the seed method via organic linker molecules. We also got preliminary results of FCS based on our integrated system although fine optimization of excitation light source and surface modification of the metal nano structures are required.
