Education and Research Activities in the Laboratory

We are advancing our research on sensor and device-related fundamental technologies such as microfabrication. We take advantage of these technologies to then conduct research on various devices such as electrophoresis chips, cell culture chips (Fig.1), microreactors, electro-osmotic pumps, and vapor-liquid separation chips. Additionally, we are furthering research on biomaterial especially for tissue engineering (Fig.2) and Gamma-ray image sensor systems (Fig.3) to be applied in the medical diagnosis field, as well as working on the integration of these technologies to realize highly functional ultra micro chemical analysis systems (μTAS: Micro Total Analysis Systems).

Research Theme

Taking advantage of semiconductor manufacturing process technologies to apply micromachining to silicon and glass substrates of sub-micron dimensions, we develop functional devices with one-micron sized three dimensional structures that are used for chemical analysis and chemical manipulation (reaction or extraction).

We are also active in the medical diagnosis field, focusing on molecular imaging technology and X-ray imaging systems. We pursue the application of molecular imaging-related technologies such as positron emission tomography (PET) to medical diagnosis fields including cancer detection at its earliest stages. X-ray imaging systems are an important technology in the medical diagnosis field and we are investigating a phase contrast imaging system using an X-ray Interferometer.
Our laboratory research themes include:

1. Microchemical analysis systems

2. Microreactors and micropumps

3. Biomaterial for tissue engineering

4. Molecular imaging: Positron emission tomography

5. X-ray imaging systems
