• Project title
  • DNA ciliate

• Abstract
  • A living cell is an ultimate highly-functional molecular robot. The high functionality is caused by not only their various nanometer-sized functional molecules but also its “micrometer-sized” body that can possess the molecules. However, the size of already-developed molecular nano-robots is too small to include multiple functions. Toward highly-functional molecular robots, it is acquired to construct molecular robots with micrometer-sized body. Here, we propose an autonomous DNA molecular robot “DNA ciliate”. A natural ciliate has a micrometer-sized body with cilia and achieves various functions such as autonomous motion with the cilia, phototaxis, etc. DNA ciliate has a micrometer-sized body with many DNAs as cilia, and it can switch three different modes in response to its external environment: the free moving mode, the mode of walking on tracks, and the mode of gathering at light-irradiated positions. We believe our concept will promote the construction of highly-functional molecular robots like cells in future.
