Quantum effects and magnetism in the spatially distributed DNA molecules

Highlights: • Electronic and magnetic properties of metal-doped DNA structures are reviewed. • Unusual magnetism of gadolinium and copper doped DNA systems is treated. • The classical and quantum transport in biological systems is discussed. Electronic and magnetic properties of DNA structures doped by simple and transition d- and f-metal ions (Gd, La, Cu, Zn, Au) are reviewed. Both one- and two dimensional systems are considered. A particular attention is paid to gadolinium and copper doped DNA systems, their unusual magnetism being treated. The problem of classical and quantum transport (including transfer of genetic information during replication and transcription) and electron localization in biological systems is discussed.
