Outline of Final Research Achievements

The establishment of a method (DDS) for selectively delivering a drug to a target site using nano-sized particles can be expected to enhance the effect of the drug and reduce the side effects. Therefore, in this research, we focused on DNA nanostructures and examined the creation of Dendrimer-like Nucleic Acid Nanostructures (D-NANs) that can construct spherical structures with arbitrary diameters. As a result, we succeeded in confirming the construction of the second generation D-NANs. In addition, since the created structure is to be observed with an atomic force microscope, observation using DNA origami technology was tried, and the structure was successfully created and observed.

Academic Significance and Societal Importance of the Research Achievements

目標とする部位に薬物を効率よく送達することで薬の効果的な利用と副作用の低減の両立を図るため、様々なキャリアを用いて薬の送達を行う技術がドラッグデリバリー(DDS)である。本研究では核酸ナノ構造体がどのように細胞へ取り込まれるのかを解明するため、新たな構造体D-NANsの創生を試みた。その結果三角柱型の核酸ナノ構造体TP-Aを用いて移行経路がを蛍光顕微鏡によって明らかにし、第2世代までのD-NANs創生に成功した。この研究はDDSのキャリアとして期待される核酸ナノ構造体の細胞内動態を明らかにすることを試みるものであり、次世代の創薬に貢献するものである。
