1A2-B07 Function Emergence of Cellular Build up Wet Nano Robotics : Development of Carbon Nano Coil Based Nano-Machine and Application to Cell Manipulation by Three-Dimensional Magnetic Field(Nano/Micro Manipulation System)

Abstract

In this paper, a novel application of Carbon Nano-Coils (CNCs) as intracellular nano-robots is described. We succeeded in fabricating nano-robots made of CNCs, and disperse them in water by coating 2-methacryloyloxyethyl phosphoryicholine (MPC) polymer. Then, it swam in medium with magnetic field generated by three pairs of magnet coils facing each other. The facing magnet coils generated a uniform magnetic field between themselves, and its magnetic flux density was 5 mT. The obtained CNC had dimensions of 700 nm (diameter), 250 nm (thickness), 350 nm (pitch). They swam by rotating their body in the velocity of 1.74 μm/s, the thrust force of 0.1 pN, and successfully control its direction of movement by switching magnetic field.
