| Outline of Final Research Achievements |
We investigated the development of a new electrochemical virus sensor with virus infection as an indicator by covering a conductive element with a biological membrane that mimics cell membranes. According to the original research plan, various functional peptides including sensor element binding peptide, biological membrane binding peptide and virus binding peptide were identified and applied for the sensor development. Using these peptides with pore sensor electrochemical devise, it was successfully shown that one influenza virus can be detected with the potential of the species identification. By carrying out detailed comparative analysis between active and inactive viruses, new reliable virus sensing devices without false positive detection can be developed in near future.
