Advanced Medical Science(Cooperating field)Nanoengineered Molecular Diagnostics


Nanobiodevice is a piece of contrivance, equipment, machine, or component, which is created by the overlapping multidisciplinary activities associated with nanotechnology and biotechnology, intended for biological, medical, and clinical purposes. During the past decade, nanobiodevice has progressively begun to focus on the establishment of main four fields of biomedical applications of nanotechnology, including 1) diagnostic devices, 2) molecular imaging, 3) regenerative medicine, and 4) drug delivery systems. The research efforts in my laboratory have been focused on the development of novel nanodevices, nanomatrials, and nanotechnologies intended for biomedical applications, including genome and proteome analysis, analysis of biomolecules and cells, diagnosis of diseases, in vivo imaging, stem cell therapy, tissue engineering, and gene delivery system, as shown in Fig. 1.


Research Projects

The research in our laboratory has been supported by Cabinet Office’s Funding Program for World-Leading Innovative R&D on Science and Technology (FIRST), Cabinet Office’s Impulsing Paradigm Change through Disruptive Technologies Program (ImPACT) (Fig. 2) and MEXT Center of Innovation

Science and Technology based Radical Innovation and Entrepreneurship Program (COI-STREAM) (Fig. 3). Since nanobiodevice has tremendous advantages, it is applicable to fast analysis of biomolecules. Nanopillar-nanopore integrated nanobiodevice enables us to develop ultarafast single molecular DNA sequencing as shown in Fig. 4 and nanowire-nanopore devices combined with machine learning technique enable us to develop mobile sensors for PM2.5, bacteria, and virus in the environment.

AMED translational research network program (Fig. 5) supports us to develop immuno-wall devices realized the fast and low invasive “from blood to analysis” type biomarker detection of cancer with fM detection sensitivity within 2 min (Fig. 6) and the synchrotron radiation based nanofabrication technology enables us to develop highly sensitive immno-wall devices supported by Aichi Prefectural Funding Program for Priority Research Area (Fig. 7).

AMED next-generation cancer diagnostic system program (Fig. 8) supports the development Nanowire devices coupled with super-resolution optical microscopy are extremely useful to analyze exosomes from cancer cells and exosomal microRNA analysis(Fig. 9).

AMED research center network for realization of regenerative medicine (Fig. 10) makes us to develop quantum-biodevices for single cancer cell diagnosis, single molecular epigenetic analysis, quantum switching in vivo imaging for iPS cell (induced pluripotent stem cells) based regenerative medicine, and theranostic devices for cancer diagnosis/therapy(Fig. 11).
