WHO ARE WE?
Welcome to our website
We are a team of undergraduates from Japan.
The concept of our project is "Big ambition of tiny car". It derives from slogan of Suzuki company. This company produced car. Their cars were small but performed highly. In Japan, it made people spread cars and became the foundation for popular car. In short, it opened up possibilities for Japanese car industry. We also produced car. And, it is not metal but DNA. Indeed, our car may be tiny and helpless now, but we believe also our car will expand the possibility for molecular robotics in the future.
Finally, we really appreciate your visit. Please enjoy our site.
In recent years, DNA Origami is attracting attention. It is an innovative technology that allows free design and creation of desired nanoscale structures. DNA Origami is expected to be applied to various purposes such as molecular robots. One interesting example of molecular robots is “Nanocars”.
Here, we propose a Nanocar made with DNA Origami technique. First, we designed DNA sequence for one-wheeled car body and will make DNA Origami based on this design. Next, two of the car bodies will be connected by appropriate staple strands to create “DNA Origami Bicycle”. Finally, staple strands with azobenzene moieties will be introduced to crosslink the tire and shaft. With this azobenzene-tethered DNA, formation and dissociation of a DNA duplex can be reversibly photo-regulated by cis–trans isomerization of the azobenzene. By using this mechanism, we can achive control of driving.
In the future, we will challenge car racing by DNA nanocar.
