| Outline of Final Research Achievements |
A rapid and versatile immobilization method using an adhesive protein for peptides, proteins, and liposomes onto material surfaces was developed. Furthermore, we clarified the effects of the adhesive protein-coated surfaces on cell adhesion and proliferation. The adhesion of the adhesive protein to the material surface was observed in water by AFM, measured by quartz crystal microbalance (QCM), and analyzed by all-atom molecular dynamics (MD) calculations to gain insight into the adhesion modes.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で確立した表面修飾技術は、AtaAに機能性ペプチドやタンパク質、リポソームなどを融合し、化学修飾をしていない任意の材料基盤に水中接触させるだけで固定化するという、迅速かつ簡便な産業界待望のものである。また、本研究で明らかになったAtaAの接着様式は、生体分子-非生物表面間相互作用の原理解明と制御に向けて非常に重要な知見である。
