Outline of Final Research Achievements |
In this study, we prepared a functional double-layered nanosheet with a hollow structure by site-selective process of surface modification, molecular introduction, and exfoliation using layered hexaniobate. Functionalities of the nanosheets was evaluated to use as a two-dimensional nanocapsule for drug delivery systems. Gadolinium ions were loaded into the nanosheet interlayers, and biocompatible polymers were modified on the nanosheet surfaces. The obtained sample showed high dispersion stability in water and markedly shortened the magnetic relaxation time of water compared with the absence of nanosheets, suggesting the possibility of application as a contrast agent nanocarrier.

Academic Significance and Societal Importance of the Research Achievements |
本研究で開発した2層ナノシートは、層状化合物に特有の層間イオン交換性とナノシートの2次元性を併せ持つ新規なナノ材料であり、その中空かつ平面的な構造特性は過去にないDDSナノキャリアとして学術的な独創性を持つ。また、本研究で実現したナノ構造体の位置選択的な表面修飾は、ナノ材料に付与した機能を効果的に発揮するパターニング技術としても利用価値があり、様々な分野におけるナノ材料の応用研究において波及できる技術である。
