研究課題	構造転写プロセスによるアシンメトリー機能材料の創成
研究組織	研究分担者：鎌田香織（防衛医科大学校医学教育部・講師) 研究分担者：金仁華（神奈川大学工学部・教授）
研究内容	本研究では、独自に開発したバイオテンプレート法とキラルシリカ転写法を基盤技術に、アシンメトリー構造の転写、アシンメトリー機能の開拓、アシンメトリー材料の創成をめざす。具体的には、①らせん藻類スピルリナのバイオテンプレート技術による金属マイクロコイルとその分散シートの作製、およびそれらのアシンメトリー機能探索、②不斉有機酸/ポリエチレンイミン（PEI）錯体から誘導されるキラルシリカを母体とする無機材料への不斉転写プロセスの開発とアシンメトリー機能探索を行う。作製プロセス開発は、量産性、材料汎用性、構造制御性に注力し、アシンメトリー機能は、スケーリング則に基づいた光を含む電磁波応答や触媒など化学的不斉機能に加えて、近接場の利用、力学的応答、並進・回転など運動挙動など広義のアシンメトリーを探索する。
専門分野	ナノ・マイクロ材料化学、高分子化学、化学プロセス
研究キーワード	バイオテンプレート、キラルシリカ、ナノ・マイクロコイル、個体円二色性、ヘリカルアンテナ理論
