細胞内刺激を目指した磁気駆動型ナノマシンに関する研究

抄録

In this paper, we proposed an intracellular nanomachine for controlling an organelle and a cell function. Carbon nanocoil sputtered Ni was used as a nanomachine. The nanomachine can be driven by rotating magnetic field. In order to optimize the driving performance, the velocity dependence on the Ni thickness was evaluated and we tried to introduce a nanomachine into a cell. As a result, the maximum velocity of 2.8 μm/s was obtained for Ni thickness of 80 nm. We found that the optimized Ni thickness existed for the nanomachine. Furthermore we succeeded in the introduction of the nanomachines into a cell and driving the nanomachines inside cells. These results will lead to smaller nanomachines to investigate the information inside cells.
