Furthermore, by way of forming a piezo-electric film 32 on the surface of the nanotube 9, and the tip ends of the nanotubes are freely opened and closed by expanding and contracting the piezo-electric film, thus allowing any desired nano-substances to be handled regardless of whether the nano-substances are insulators, semiconductors or conductors. Furthermore, if by way of designing three nanotubes so as to be freely opened and closed by an electrostatic system, nano-substances of various shapes such as spherical, rod-form, etc. can be handled. Moreover, a nanomanipulator that is constructed by combining the nanotweezers with a three-dimensional driving mechanism facilitates the gripping, moving and releasing of nano-substances.
