Background of Project
- DNA Screwプロジェクトの目標は、DNAのみで回転するモーターを作ることです。生体分子を利用して自発的に動く仕組みに関しては、モーター蛋白質Kinesinの研究やDNAの「歩行」運動、あるいは昨年度のTitech Nano-Jugglersが発表したBiomolecular Rocketなど、これまでに数多くの研究が行われてきました。しかし、DNA純正で回転運動を実現したものはありませんでした。
- 回転運動をする機構、すなわちモーターは、高い応用可能性を秘めています。例えば実生活のスケールの世界では、スクリュー、自動車、洗濯機、時計、ファン、果てはゲーム機のコントローラーなど、あらゆる場面で用いられています。私たちは、この回転運動をDNAのスケールでも実現することで、今後のDNAエンジニアリングの幅が大きく広がるのではないかと考えました。
- 当然のことながらDNAモーターは、実生活スケールのそれとは、そのメリットや活用範囲も大きく異なってきますが、それでも数多くの可能性を秘めています。DNAモーターを自由に制御する技術が完成すれば、既存のセンサーなどと組み合わせて、完全自立型の分子ロボットを作ることもできるかもしれません。以降、モーターの構造の説明や活用方法のアイデアを紹介します。
Project Overview
- The motor made in this project comprises three parts, including the cylinder as an axis, DNA Spiders as a source of power and the ring which actually rotate. At the first phase in the project, we design each parts and confirm their suitability for the motor by experiment. Then, in the second phase, we develop a method to combine each pasts and make up the motor.
- If you need details of each experiment, please click ">>read more" link and jump to Design page.
(Phase 1)
Cylinder
- The cylinder is put in the center of the motor as an axis supporting the rotation. The material DNA is formed into a cylindrical shape using DNA Origami technology. >>read more
DNA Walker
- The sources of power in rotational motion is DNA Spiders. DNA Spider consists of three DNA Walker which moves on footing by taking strands after another with DNAzyme. As they orbit the cylinder, their rotational movement is transmitted to DNA Ring. >>read more
Rotary Ring
- It is the DNA ring part that actually rotates. It has shape like the side surface of a disk, and is also composed with DNA Origami technology. >>read more
(Phase 2)
Motor
- The motor is realized by assembling above thee parts: Cylinder, Spider, Ring. Unlike motors in electrical work, rotary parts of our motor is outer ones and the central cylinder are fixed. >>read more
Another Structure
- The motor made in this project rotates by DNA spider and round footings. In this system, the cylinder become too long if motor make many revolutions. However, we have an idea which make it possible to make lasting rotation by using long straight footing and DNA spiders positioned circularly.
