Physical properties of natural DNA and metal ion inserted M-DNA

摘要

DNA has attracted much interest as a material for nano science and technology. We have studied DNA both in natural forms and modified forms M-DNA by insertion of a variety of metal ions. On the ground of basic science, we tried to unveil the intrinsic physical properties, espeeially magnetic properties of natural DNA and a possibility of charge carrier doping by the metal ion insertion. Diamagnetic nature of natural DNA and a variety of features in M-DNA will be presented.
