For developing functional nanomaterials such as nanowires, we have engaged in synthesizing DNA structure based one dimensional metal complexes (metallo-DNA nanowires). We have reported a crystal structure of Ag-DNA wires in which silver ions are uninterruptedly arrayed in DNA duplexes, and a crystal structure of Hg-DNA wires. Also, we have developed a procedure for preparing DNA duplex in which Ag ions were accumulated in a high density. The reports have been published in highly rated scientific journals and a structure was selected as a cover picture.
We have started to prepare metallo-DNA wires which are stable in solutions. Also, we have started to measure electrical conductance of DNA duplex having metallo-base pairs.
