Outline of Final Research Achievements

Nonlinear waves generated by reaction-diffusion coupling (reaction-diffusion wave) is a mechanism underlying molecular placement within cell. However, analysis of reaction-diffusion waves in cell-size space is challenging due to its complexity, and therefore, verification by model experiments was needed. In this study, we used a system that generates reaction-diffusion waves in artificial cells and investigated the characteristics and principles of reaction-diffusion waves in cell-size space. Through the 3-year research, We elucidated the characteristics of the reaction-diffusion wave adjusting its shape according to the spatial size and the mechanism controlling the motion of the wave.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果により、従来大きな空間での振る舞いのみが解析されてきた反応拡散波が、細胞のような小さな空間でどのような性質を示すか、が導かれた。この成果は生物の細胞において分子の配置がどのように決定するか、という理学的な知見だけでなく、細胞サイズの空間をどのように制御するかという材料科学・工学的に重要な知見ももたらす。将来的にはナノ・マイクロ空間における自在な分子配置につながり、生命から医薬・化学品の創成原理まで広く波及することが期待される。
