Prof. Takao Someya (Graduate School of Engineering) and his colleagues, in collaboration with Tokyo Women’s Medical University, have developed a nanomesh sensor with high elasticity and flexibility, and succeeded in measuring the surface potential of cardiomyocyte sheets. Even when in direct contact with human iPS cell-derived cardiomyocyte sheets, the dynamic beating of the cell sheets was not inhibited by the sensor, and stable measurement was achieved over a long period of time. It is expected to be applied to drug discovery and regenerative medicine of cardiac muscle sheets in the future. The resultant paper was published in the electronic edition of Nature Nanotechnology on December 31 (UK time).
