Background and Motivation

In recent years, technologies that operate or process minute objects precisely are becoming more and more necessary in the field of engineering. It goes without saying that many researchers are now trying to design DNA origami which has advanced functions and complicated structures by designing nanoscale sequences of base pairs of DNA. In addition, a technology that gives new functions and structures to a carbon nanotube which is a good conductor of electricity and can contain variant molecules by bending them.

However, these techniques such as processing DNA or carbon nanotubes mentioned above are the technologies that make the most of properties of the materials. Therefore, the techniques are applicable only to DNA, carbon nanotubes, respectively. Even if a technology that operates carbon nanotubes in nanoscale accuracy (of course it is also important, though), the technique is no use when it comes to engineering other polymers such as cellulose or poly-lactic acid

Unfortunately, there is no technology which is generally applicable to a variety of polymers so far. Our team tried to develop a new technology which can operate and process simple polymers without depending on the physical and chemical properties of the target polymers as a piece of a universal technique. We decided to utilize DNA as a material for the aforementioned development because considerable amount of know-how of dealing with DNA is being accumulated in the last 30 years. DNA is a promising material.
