| Outline of Final Research Achievements |
We have determined three-dimensional structure of a metallo-DNA with uninterrupted one-dimensional (1D) metal-array. In this crystal structure, the DNA duplexes containing a 1D metal-array further formed a pseudo-continuous duplex according to the crystal symmetry. This means that 1D metal-array is continuously formed from one edge of the crystal to another edge. We succeeded in creating a 1D metal-array of a visible length. It should be also mentioned that none could obtain such a long metallo-DNA until now, although many researchers have made a lot of trials all over the world. From now on, using this crystal, we were able to examine electrical properties like a conductivity of a 1D metal-array in the long metallo-DNA. In conclusion, we were able to report truly long molecular nanowire made of metallo-DNA molecule, for the first time.
