| Outline of Final Research Achievements |
As a technique to draw 2D and 3D integrated patterns of inorganic nanoparticles such as carbon nanotubes and graphene, we proposed a method of using organic molecular aggregates as a soft template and demonstrated it in this study. It was revealed that molecular aggregates in which surfactant molecules self-assembled in water and a polymer aggregate in which phase separation occurred in a poor solvent had deformable and flexible functions and were used as the templates. A top-down determined integration patterns of inorganic nanoparticles were successfully drawn by our proposed method.

| Academic Significance and Societal Importance of the Research Achievements |
ナノテクノロジー技術の振興により、カーボンナノチューブを含め多種多様なナノ粒子が合成されている。こうしたナノ粒子をデバイスや機能材料に応用するためには、マクロスケールなレベルにまで接合・集積させると同時に、任意のパターンに加工しなければならない。本研究では、汎用の３Dプリンタのようなシンプルな方式にて、ナノ粒子をCAD等で設計した2次元あるいは3次元の集積パターンに描画する方法論を提案し、実証した。
