Abstract:
Nanotweezers characterized in that said nanotweezers comprise: a plurality of nanotubes fastened at base end portions thereof to a cantilever so that said nanotubes protrude tip end portions from said cantilever, fixing means that fasten said base end portions of said nanotubes to a cantilever by a coating film or a fused portion, insulating coating film formed on a surface of said tip end portions of said nanotubes that prevents short-circuiting between said nanotubes and nano-substance to be gripped, and electrodes that are electrically connected to at least two nanotubes among said nanotubes; wherein said tip end portions of said at least two nanotubes are freely opened and closed by means of an electrostatic force created by applying a voltage across said electrodes.
