| Outline of Final Research Achievements |
The objective of this research project was to apply Drug Delivery System (DDS) technology, which has been pioneered in the medical field, to plants. Considering the eventual agronomic application, we focused on nanoparticles from various DDS technologies. As a method for nanoparticles of essential plant elements, we employed supercritical technology, which is a clean method. As a result, they succeeded in producing highly dispersible nanoparticles, which were introduced into plants by foliar spraying, and confirmed high introduction efficiency and differences in localization within plants. Furthermore, when the active ingredient was added to the nanoparticles and introduced into the plant, the efficacy was successfully confirmed at lower concentrations.

| Academic Significance and Societal Importance of the Research Achievements |
本研究成果は、これまで農学分野で応用されてこなかったDrug Delivery System (DDS)技術を使用することで、既存の農薬・肥料の使用量削減につながると同時に、新たに作物生産に有用な物質を直接導入できる技術へと繋がると思われる。特に導入後の局在性が作物種ごとに異なることやナノ粒子によってその局在が変化することは大変興味深く、応用的な利用に加えて、導入後の細胞間の移動プロセスなども今後の研究課題となると考えれ、これまで議論されてこなかった人工的に導入された物質の輸送性など新たな分野の創出も期待される。
