Research Outline
Since biological systems, including the brain, function based on the transport of ions and molecules rather than electrons, artificial devices that directly interact with biological systems need interfaces capable of not only electrical interactions but also the exchange of chemical substances. Such interfaces are important for treating various diseases. Therefore, devices that mediate between biological systems and artificial machines need to accurately and efficiently control the ion and molecular transport phenomena.
To date, I have conducted fundamental research on the transport phenomena of substances at the micro- and nanoscale, primarily through experiments and theoretical considerations. Over the past 20 years, the field of nanofluidics has made significant advances, and we have gained an understanding of how ions and molecules are transported in confined spaces. Hence, by integrating the transport phenomena of ions and molecules studied in the field of nanofluidics with the field of biomedical devices, I will advance the creation of nanofluidic iontronic devices based on an understanding of fundamental physics. Iontronics, as mentioned here, is a general term for research that aims to achieve intelligent behavior by precisely controlling the transport of ions, much like electronics deals with the movement of electrons. Utilizing various micro-nano processing technologies, I will particularly focus on the development of implantable ion pumps for medical use and neuromorphic devices.
