Localization and delocalization of charges injected in DNA
Thomas Heim, Thierry Melin, Dominique Deresmes +1
The electrical properties of DNA molecules are investigated by charge injection and electric force microscopy experiments. Prior to injection, DNA molecules exhibit a weak positive…

Conductivity of DNA probed by conducting-atomic force microscopy: effects of contact electrode, DNA structure, surface interactions
Thomas Heim, Dominique Deresmes, Dominique Vuillaume
We studied the electrical conductivity of DNA molecules with conducting atomic force microscopy as a function of the chemical nature of the substrate surfaces, the nature of the el…
