| Research Abstract |
For in-situ single-molecule fluorescence imaging of membrane proteins, we investigated the structure of nano-waveguides using computational optics simulation, followed by fabrication of the waveguides on glass substrates. We studied the feasibility of the waveguides for real-time single-molecule imaging in relation to the waveguide structure. We have developped processes for the fabrication of both etched waveguides and planer waveguides. We showed that the protein-protein interaction can be fluorescently detected with the etched waveguide, and also that the signal-to-noise ratio of the etched waveguide is six times the conventional waveguide. Although we have not yet succeeded in observing menbrain protein interaction using the palner waveguide, we constructed the elemental techniques for the observation, and have succeeded in detecting the single-molecule fluorescence using the planer waveguide.
