Our group aims to perform interdisciplinary research combining nano/bio materials with mechanical engineering. The main research tools are self-organization, 2D materials including graphene, and in-situ TEM (transmission electron microscopy). We use these tools not only to study scientific principles in nanoscales but also to develop engineering devices including biochips and nanorobot. Our research interests are classified into three fields of nano/micro fabrication, bionano devices, and in-situ TEM.

In the nano/micro fabrication research, we focus on generating nano/micro scale patterns on 2D materials including graphene using self-organization of nano/bio materials. We also develop a versatile method of controling the fabricated nano/micro patterns using microfluidic devices, which can control the self-organization reactions.

In the bionano device research, we apply the developed nano/micro fabrication techniques to manufacturing bionano devices for biomedical devices. The application area includes high-throughput analysis tools and biomedical platforms for tissue engineering.

In the in-situ TEM research, we plan to investigate nano and/or bio phenomena with real-time nanoscale imaging. The 2D materials provide membrane platforms suitable for electron microscopy, and observation targets include self-organization processes in nanoscales, interface/interaction between bio and inorganic materials, liquid-phase samples, nanofluidic self-assembly, and nanoparticle physics. The in-situ TEM research can deliver fundamental atomic-scale information about the relationship between mechanical/biochemical properties and nanophysical phenomena, thus giving huge impacts on both fundamental science and applied engineering.
