| Outline of Final Research Achievements |
Far-ultraviolet (FUV, <200 nm) surface plasmon resonance (SPR) sensor using Al film was developed.
First, Al-SPR properties depending on refractive index changes on the Al surface were investigated by depositing bulk-liquid samples such as water and alcohols. In addition, larger SPR wavelength shifts were revealed by adding resonant-molecules. Subsequently, organic film formations with nano-meter thickness were detected as SPR wavelength shifts. Finally, bio-sensing using antigen-antibody reaction was tested.

| Academic Significance and Societal Importance of the Research Achievements |
表面プラズモン共鳴センサーは、すでに可視光を利用したバイオセンサーとして普及している。本研究で目指した紫外光を利用したセンサーは、従来と比較して高いセンサー感度、表面選択性、物質選択性を期待できる。本研究期間中に、モデル系による実証を終え、より応用的なバイオセンサーとしての検討にまで着手した。今後本技術が確立することで、上記3つのアドバンテージを兼ね備えた新しいセンサーの開発が期待される。
