Outline of Final Research Achievements

Single-wall carbon nanotubes are synthesized as mixture of various structures with different arrangement of carbon six-membered rings. In this research, focusing on the function of surfactants, we have developed a new method for separating metal type and semiconductor type from mixtures of various structures. At the same time, this method can automatically sort the semiconductor type to exactly the same six-membered ring arrangement including right- and left-handedness, with high efficiency, high purity, and large scale. Using a single structure nanotube separated by this new method, detailed electronic band structure of each structure was first experimentally revealed from the circular dichroism spectrum. We also found a new function of nanotubes that enable selective fluorescent imaging of mouse brown adipose tissue.
