Research Abstract	本研究課題は、新規の電極材料として多方から注目されている導電性ダイヤモンド薄膜の(光)電気化学的特性を明らかにし、その応用として生体関連物資の超感度センサーや新しい電池材料を確立することを目的とするものである。ダイヤモンド薄膜は、その高速応答性や広い電位窓など、従来の電極材料と比較して格段に優れた特性を有しており、これまでにない新しい電気化学反応・概念の確立が期待できる。特に、ダイヤモンド電極を使用することで、従来は生体内での分離検出が不可能であった物質のいくつかが容易に微量検出できることが明らかとなっており、その機能解明を含めて、応用的発展が望まれいるが、本年度は特に、韓国・ソウル大学・Kim教授、Chungbuk大学・Park教授、研究分担者でもある、プエルトリコ大学・教授も来学し、高度な専門知識を有しいる光電気化学特性について討論を重ね、今後の研究成果の展開が多いに期待できた。下記について基礎手法の確立を目指して研究を遂行してきた。本年度の成果も目的をほぼ達成できた。 1.ダイヤモンド薄膜の作成 2.膜の安定性と固定化の評価 3.電気化学特性評価 4.ナノスケールでの表面構造観察 5.種々の分光法を用いたダイヤモンド薄膜の特性評価の確立 6.ダイヤモンドのドライエッチング法の開発とその評価 7.光電気化学特性の評価 8.振動分光法によるダイヤモンド電極における表面変化のその場観察
