▎ 摘　　要

NOVELTY - Nano-motor structure driven by electroosmotic flow comprises an electroosmicroporous system, an annular single-stranded DNA transmission system and a nano motor system. The electroosmolsis system includes an electrolyte solution, a single-layer graphene film and an external electric field perpendicular to the single-layers graphene film. The electrolyte comprises anion (101) and a cation (104). The two sides of the single layer graphene film are provided with nano holes. The one nano-hole wall surface is provided with negative electricity, and the other nano-holes wall surface with positive electricity. The annular double-wall carbon nanotubes are provided on the nano-molar system. USE - Electro-osmotic flow driven nano-motor structure for diagnosis and treatment of various diseases. ADVANTAGE - The nano-motor system with simple structure, convenient operation, accurate control and quick response is provided. The electroosmosis drives the annular single-stranded DNA molecule to rotate and transmits the power to the carbon nano-tube motor through the single-layer graphene film, which realizes the simplification operation and accurate control of the nano motor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the electro-osmotic flow driven nano-motor structure. 101Anion 102Single-layer graphene film 104Cation 105Nano-hole with positive electricity
