| Outline of Final Research Achievements |
Sensors utilizing field effect transistors (FETs) have attracted attention as bio and ion snsors. Single-electron transisotrs (SETs) are a promising candidate for achieving high detection sensitivity due to their Coulomb oscillation. In this study, the mechanism of ultra-sensitive biomolecule detection utilizing a SET sensor has been clarified by experimental and theoretical analyses. In addition, immunodetection of prostate-specific antigen(PSA) has been perfomed utilizing a SET sensor, demonstrating the suitability for practical use.
