| Outline of Final Research Achievements |
This study aims at realization of single-electron tunneling in lipid bilayers as a new sensing principle. We first examined incorporation of nanoparticles into lipid bilayers and found that only very small nanoparticles could be incorporated into self-standing bilayer lipid membranes. We next examined simulation on single-electron effects of aligned nanoparticles and revealed that observable single-electron effects would be possible even at room temperature. In addition, we have established fabrication procedures for silicon chips with wired metal electrodes. We would like to combine these techniques to realize single-electron tunneling in lipid bilayers and apply to highly sensitive biosensors to demonstrate a novel sensing principle.
