| Outline of Final Research Achievements |
Utilization of organic and biological materials is important for sustainable future civilization. Our project is an approach to replace inorganic materials used in electronic and photonic devices with organic resources of biological origin which is intrinsically renewable. Among biomaterials, DNA with doubly helical structure is suitable to incorporate functional dyes which play important roles in functional devices. Along the concept, we have studied laser devices based on DNA, and in this project developed compact and wavelength tunable dye lasers by introducing light emitting molecules and photoactive molecules into DNA based polymer films. The products were fabricated with a relatively simple manner, showing high performance and good durability which is the most important properties achieved in this project. The developed laser sources will be useful for application in clinical medicine, environmental research and so on.

| Academic Significance and Societal Importance of the Research Achievements |
持続可能な未来を築くには、再生可能な資源を高度に活用する必要がある。材料面からのアプローチとしては鉱物由来の物質を、軽量安価な生体由来のものに置き換えることは有意義である。現在、有機材料によるティスプレイ・光源が普及しつつあるが、生体材料の持つ機能性を活用することも重要である。われわれはこのような観点からDNA材料を基本とする軽量簡便なレーザー素子の開発を目指し、本研究において実験室レベルにおいて一定の成功を得た。
