Nanopore Design Research Group

To support the realization of a sustainable circular society, we conduct research and development on the preparation of nanoporous materials with nanometer-scale pores, advanced structural characterization techniques, and applications such as sensing. We also actively promote the international standardization of nanomaterials.

Main Research Subjects

1. High-sensitivity, high-precision PCR technologies

By controlling the pore size and surface hydrophilicity/hydrophobicity of mesoporous silica based on enzyme size and surface properties, we have developed PCR technologies capable of accurately amplifying nucleic acids at the single-molecule level. By enhancing enzyme stability and durability, we successfully achieved improved resistance to reaction inhibitors and long-term storage stability at room temperature.



2. Sensor development using graphene-coated porous silica spheres

We are developing compact sensors based on PB/G/PSS materials. By using PB/G/PSS as a reference electrode, silver (Ag) contamination at the working electrode has been successfully suppressed, significantly extending the lifetime of compact oxygen sensors. Furthermore, when PB/G/PSS is used as a working electrode, the decomposition potentials of dissolved oxygen and vitamin C are shifted, enabling the development of precious-metal-free glucose sensors that do not require interference removal devices.



3. Multi-probe crystal structure analysis of materials with nanoscale confined spaces

We are analyzing the crystalline structures of inorganic nanoporous materials such as zeolites, which regularly include nanometer-scale pores, by a complementary combination of powder X-ray diffraction/scattering, solid-state NMR, three-dimensional electron diffraction (3D-ED), and electron microscopy techniques. This approach enables the evaluation of average and local structures, multiphase compositions, crystal morphology, and structural defects from submicron-sized crystals, supporting research on new material discovery, precise structure–property relationships, and the analysis of scarce samples.
