Researcher Interview Vol.2, “Microfluidic device technology that embodies medical science and engineering collaboration”
―Please tell us about your research.
My aim is to cultivate new research fields and industries by bringing micro / nano device technology specifically from the engineering field together with a diversity of other research fields. As the name implies, our micro / nano device is a small machine, and with the use of semiconductor microfabrication technology and 3D printers / plotters, we can custom design and process these micron-ranged small spaces. We are focused on integrating such devices together with biotechnology, and are working hard every day to develop systems that can be applied to medicine and drug discovery. By handling living cells and rebuilding biological functions in a small artificially created space, our research hopes to both replace animal experiments in drug discovery as well as to elucidate unknown life phenomena. Indeed, what we are developing is a hybrid mechanical-biological system. A system which skillfully combines seemingly incompatible things such as machines and living things, not only affords greater convenience for its medical applications, but it also sets the stage for new discoveries.

An article by Dr. So Nakagawa was published in Daily Gendai on April 21. “What is the difference between the new coronavirus and the 9% lethal SARS?”
Many people think of the new coronavirus as “a little heavy flu,” but it’s a mistake. In fact, it is the same coronavirus as the “Severe Acute Respiratory Syndrome (SARS) virus” with a fatality rate of 9.6%, and the genes are also very similar. How long? Interview with Dr. So Nakagawa, Ph.D., who is a postdoctoral researcher at the National Institute of Genetics, a visiting researcher at Harvard University, and a lecturer at the Molecular Life Sciences School of Medicine, Tokai University.
“The similarity of the genes that make up each virus is about 70 to 90%. However, the new coronavirus is not an evolution of the SARS virus. They are like relatives. One of the genes with the lowest similarity compared to each other is the S gene. ” The spike protein (S protein) forming the viral protrusion has the role of binding to the receptor on the surface of the infected cell and mediating the fusion of the viral outer membrane and cell membrane. The S gene has a design drawing that determines the character of the S protein and creates it faithfully.

Tokai Project Selected for AMED Translational Research Strategic Promotion Program
Mar. 24, 2020
A project run by the research group of School of Engineering, Department of Mechanical Engineering Associate Professor Hiroshi Kimura (Micro/Nano Technology Center, Tokai University) called “Building a Model for Amyotrophic Lateral Sclerosis (ALS) with Physiological Neuromuscular Junction” was recently selected as a Japan Agency for Medical Research and Development (AMED) Translational Research Strategic Promotion Program Multidisciplinary Research Development Support Project. The goal of the program is to promote the creation of innovative medicines, medical devices, and other medical-related items by constructing a system to effectively translate promising basic research results into clinical research and practical application. This particular project is implemented by the Metropolitan Academic Research Consortium (MARC), which is composed of clinical research institutions, particularly at private universities, in the metropolitan Tokyo area. The initiative is aimed at the development of innovative medicines and medical devices in Japan, focusing on projects by researchers at universities with a medical school who do not themselves belong to the medical faculty.
Associate Professor Kimura is working to develop a microfluidic device which artificially imitates nerve tissues and the functions of various organs, such as the kidney and liver. Utilizing this technology, Kimura is conducting joint research with School of Medicine Professor Shinji Hadano and Assistant Professor Asako Otomo to explain the mechanisms behind ALS. Through the project chosen by AMED, they hope to further develop their research.

Tokai University Micro / Nano Research and Development Center Researcher Interview
“Fascinated by the physical universality of soft materials and system-dependent diversity”
Rio Kita. Professor, Department of Physics, Faculty of Science, Micro and Nano Research and Development Center, Tokai University
(Published on Feb 2020, interviewed by Takahashi and Mori)
―Please tell us about your research.
If I roughly divide my research,
① Study on phase equilibrium and phase separation dynamics of polymer solution
② Analysis of blood rheology and gelation of plasma proteins
③ Characterization of polymer (Study on molecular properties in thermal equilibrium)
④ Analysis of irreversible transport phenomena in non-equilibrium phenomena of polymers
⑤ Molecular dynamics analysis of soft materials
In short, it means “to study the properties of soft substances at the molecular level.“
Since joining Tokai University in 2005, I have been conducting molecular dynamics research on soft materials as a member of the Dielectric Spectroscopy Group with Prof. Shin Yagihara and Prof. Naoki Shinyashiki of the Department of Physics. Soft materials containing water (synthetic polymers [Ref. 1-7], gels [Ref. 8-11], biopolymers etc. [Ref. 12-16], mixed solution of low molecules [Ref. 17-19], ultra thin polymer film we have been studying the molecular properties of dispersions,using various methods such as laser interferometry, light scattering, small-angle X-ray scattering, thermal analysis, viscoelasticity measurement, and broadband dielectric spectroscopy.
As a subject of physics, we are actively adopting basic research on the structure and function of biological macromolecules such as polysaccharides, nucleic acids, and proteins, which are complex systems, and methods and methodologies of polymer physics. In addition, it will be quite challenging in terms of physics. Based on this, we also conduct molecular biology research and research aimed at industrial applications. Recently, in cooperation with the teachers of the Micro / Nano Research and Development Center, we are focusing on fusion research between humanities and science, and hope to return the results to education.
－Please tell us about your activities at the Micro / Nano Research and Development Center.
In 2014, adopted the Private University Strategic Research Support Project “Next-Generation Medical Technology Created from Ultrathin Polymer” (5 years in Tokai University ) by the Ministry of Education, Culture, Sports, Science and Technology, I was involved in the establishment and operation of the company and has been conducting joint research with teachers from each department and department of Tokai University. There were many encounters, and I was able to understand the difficulty of collaborative research beyond the boundaries of the field, as well as experience its effectiveness and the impact of success. Communicating with a variety of professional teachers gives me lots of new realizations and makes me study a lot. Sometimes it’s difficult to keep up, but I feel that it’s also fun.
