Surfactants, lipids, polymers, and proteins form various aggregate structures in water. Micelles created by surfactants are well-known, but other structures such as membranes and protein folding structure can also be formed in a self-assembled manner. These self-assembled structures are closely related to the physical properties and functions of these materials. For example, the bilayer membrane formed by phospholipids is well known as the basic structure of biomembranes, and it is known that changes in the membrane structure are related to the function of biomembranes. Self-assembling structures are also deeply involved in the properties and functions of cosmetics, paints, foods, and biomolecules.

Our goal is to understand the formation mechanism of these various self-assembled structures from a physicochemical viewpoint. We are also approaching how this mechanism relates to biological phenomena and functions of industrial materials. Furthermore, we are also focusing on how “water” is involved in this process. (We want to know why water is important for life.) This is truly an area between chemistry, physics, and biology, and we are conducting research from multiple perspectives while jumping across disciplinary boundaries.

Another characteristic of our laboratory is that we approach phenomena by using a wide variety of methods, such as structural analysis using X-rays and neutrons, thermal measurement, various spectroscopic methods, various microscopic observations, and surface tension measurement. We also take on the challenge of constructing theories. Experiments using X-rays and neutrons are conducted at large external facilities (synchrotron radiation facilities). We are also conducting joint research with many other universities, research institutes, and companies.
