Outline of Final Research Achievements

Robust methods of waste biomass utilization are increasingly demanded by modern society. While most past efforts were focused on waste polysaccharide biomass, only a few studies considered the utilization of biomass DNA for the preparation of functional materials. In this study, we developed upcycling technologies for hydrothermal, microwave-assisted, and pyrolytic processing of biomass DNA to prepare functional carbon nanomaterials.
In particular, we developed synthetic methods for fluorescent nanomaterials (biodots) from DNA by hydrothermal and microwave methods and succeeded in controlling the fluorescent properties of biodots by doping. DNA-derived biodots were applied for heavy metal detection applications.
The results of this project extended the scope of DNA biomass-derived products prepared by thermal processing thus representing a valuable addition to the existing sustainable biomass processing technologies.

Academic Significance and Societal Importance of the Research Achievements

本研究は、魚の白子など廃棄バイオマス系DNAを利用した機能性カーボンナノ材料の製造技術を開発した点で学術的に重要ある。従来の多糖類バイオマス利用研究の枠を広げ、DNAを対象にした水熱処理、マイクロ波処理、熱分解法を体系的に確立して、DNAバイオマスの応用可能性を広げた。本研究は、廃棄バイオマスDNAを有用資源として活用する新技術を提供し、持続可能な資源利用に貢献している。また、DNA由来の蛍光ナノ材料を用いた水銀など重金属検出は、環境汚染監視や公衆衛生保護に役立つ可能性があり、廃棄物の高付加価値化を通じて循環型社会の実現に寄与している。
