Abstract :
In this paper, a novel application of carbon nano-coils (CNCs) as intracellular nano-robots is described. Nano-robots made of CNCs were successfully fabricated and dispersed in water by coating them with 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer. The CNCs had a diameter of 700 nm, thickness of 250 nm, and pitch of 350 nm. The nano-robots were made to swim in a medium by applying a uniform magnetic field generated by three pairs of magnet coils facing each other. The field had a magnetic flux density of 3.5 mT. The nano-robots swam at a velocity of 0.45 μm/s by rotating their body Their direction of movement was controlled by switching the magnetic field.
