Outline of Final Research Achievements

The applicants have found that heavy metal ions and pyrimidine-pyrimidine base pairs in duplexes form metal ion mediated base pairs such as thymine-Hg(II)-thymine and cytosine-Ag(I)-cytosine. In the project, for developing DNA based heavy metal ions removing membranes and nanowires in future, we have studied structures and properties of the metal ion mediated base pairs. Crystal structures of duplexes having the metal ion mediated base pairs have been solved, and electron density distributions were calculated. As application study, we developed a mercury ion removing material consisting of polystyrene and thymine residues.
