title: Local structure of M-DNA at the Nitrogen K-edge: evidence towards a metal ion induced conduction band in DNA.
abstract: M-DNA is an engineered duplex DNA that is synthesized from high doping of transition metal ions (Ni2+, Co2+ and Zn2+) into B-DNA at high pH. X-ray Absorption Near Edge Structure (XANES) of the Nitrogen K-edge shows remarkable differences between the doped and undoped DNA. A metal ion induced conduction band in the M-DNA is used to explain the XANES results.
