DNA has attracted much interest as a material for nano science and technology. To unveil the intrinsic nature of DNA both in natural form and modified forms of M-DNA with a variety of divalent metal ions. From the magnetic and optical properties, it is concluded that the electronic states of natural salmon DNA is of semiconducting. Thus, only the hopping transport via excited states or impurity site like oxygens is expected. One of the efforts to introduce charge carriers into DNA, insertion of divalent metal ions, has been studied from magnetic, optical and structural aspects. It was concluded that the divalent metal ions are inserted in between the bases of a base pair, in place of hydrogen bonds, and the charge transfer from the metal ions to DNA occurs only in the case of Fe-DNA.
