  • Metal complex type nucleic acid
    Publication number: 20070105116
    Abstract: An object of the present invention is to provide a novel structure that enables one-dimensional arraying of metal atoms and can stably exist. The present invention relates to a double-stranded oligonucleotide derivative, which contains two oligonucleotide derivatives each containing at least one nucleotide derivative wherein a base portion of a nucleotide is substituted with a metal coordination group that is resistant to oxidation and metal atoms, wherein the double strands are formed by coordination of each metal coordination group contained in each oligonucleotide derivative to a metal atom so as to form a complex.
