Patent ID: 8088739

Claim:
A nano-transport device comprising: a base, a channel-forming member attached onto the base, access channels located on opposite sides of the channel-forming member, a plurality of orientation channels each of which is formed in the channel-forming member to connect the access channels and has a width of a cytoskeletal filament, the orientation channels extending parallel with one another between the opposite sides of the channel-forming member, a plurality of cytoskeletal filaments each of which has polarity and is fixed in one of the orientation channels by a cytoskeletal filament fixing method so that they are aligned in parallel with one another, and are oriented in the same direction, and a biomolecular motor which moves on the cytoskeletal filament in a direction corresponding to the polarity of the cytoskeletal filament, wherein: the cytoskeletal filament fixing method includes the following steps: (i) depositing a biomolecular motor on a base, (ii) moving a cytoskeletal filament by means of the biomolecular motor, and (iii) inactivating the biomolecular motor by irradiating the biomolecular motor with light having a predetermined wavelength when the cytoskeletal filament reaches a predetermined position, to thereby fix the cytoskeletal filament so that it is oriented in a predetermined direction, and the biomolecular motor scan transport a substance along the cytoskeletal filament.
