Paper Abstract

We experimentally demonstrated the manipulation and transportation of nano-diamonds with diameters of 50 nm using a thin tapered fiber. When a green laser was injected from one side of the fiber and a near-infrared laser was also injected from the opposite side, nano-diamonds could be stopped on the fiber. When the balanced power for stopping nanodiamonds, we confirmed that the balanced powers were clearly different for fluorescent and non-fluorescent nanodiamonds and that for fluorescent nano-diamonds was smaller than non-fluorescent ones, which could be responsible for the difference in absorption. This result suggested the possibility that the macroscopic motion of nano-materials could be controlled based on their resonant absorption property.
