Deep-Sea Nanoscience Research Group

Our group actively work with other researchers both within JAMSTEC and elsewhere, incorporating physics and chemistry perspectives to apply an interdisciplinary approach to elucidating the structure and function of deep-sea and marine organisms as well as the physico-chemical processes in extreme deep-sea conditions. It also conducts R&D on engineering applications of such processes.

ABOUT RESEARCH

biomimetics

Biomimetics

Biomimetics, the development of technology that mimics nature, is said to hold promise of innovation on the same scale as the Industrial Revolution, and is expected to become a huge market worth 30 trillion yen by 2025. We conduct research on applying the unique structures and functions of deep-sea and marine organisms to the development of functional materials, stractural design, sensors, robotics, and other areas.

soft materials

Soft Materials

Extreme deep-sea invironments, and particularly the high-temperature and high-pressure environments of hydrothermal vents, can give rise to phenomena such as the mixing of oil and water, which would be unimaginble in nomal circumstances. We leverage the unique physico-chemical properites of these extreme environments to develop new processes for the creation soft materials including nanoemulsions and polymers.

nanobiotechnology

Nanobiotechnology

Active research is now being conducted in the field of nanobiotechnology --the development of technologies that combine elements of biotechnology and nanotechnology-- but this R&D is limited largely to medical applications such as drug delivery and regenerative medicine. We seek to discover new uses for deep-sea and marine bioresources by developing and applying ultra-sensitive sensing and other nanobiotechnologies to the research of those resources.
