| Outline of Final Research Achievements |
The aim of this project was to create "experimental physics of autonomous nanomachines" by exploring the cooperative nature inside nanomachines through the realisation of high-performance artificial molecular motors that mimic biomolecular motors. In this study, we first realised conformational-changing leg structures by DNA oligami technology. Furthermore, a motor structure combining the legs was designed. Research will continue after the grant period, with the aim of experimentally realising this structure. For the ratchet-type motor, we propose a novel mechanism that combines unidirectionality and scalability due to structural asymmetry. Detailed numerical calculations suggest that explicit structural change is required to achieve the high operating performance of a biological motor.
