Outline of Final Research Achievements

In this project we further develop three-dimensional (3D) force mapping method for biological molecules such as various proteins by the precise control of the atomic force microscopy (AFM) probe motion as well as the real-time analysis of the response signal, which allows us to visualize 3D molecular recognition forces and other several forces originating from hydration structures and/or charge density of the molecules. Thus, the novel imaging of biomolecular functions based on the physics at solid-liquid interfaces is established, which essentially advances the molecular-scale understanding of the cell physiology.

Academic Significance and Societal Importance of the Research Achievements

本研究は、生体分子間にはたらく特異結合力を単一分子レベルで直接計測することによって、生体膜上での多様な生機能、生化学プロセスを分子レベルで直接解明しようとするものであり、最先端の分子医療の確立に大きく寄与すると考えられる。また工学的にも、生体適合性材料やバイオセンサーなどのバイオマテリアル開発に密接に関係しており、産業的・社会的にもその重要性・波及効果は大きく、極めて意義深い。
