In this contribution, we have used a new approach to measure current flowing through isolated double-stranded DNA molecules, using fullerene groups to anchor the DNA to a gold substrate. Measurements were performed at room temperature in an inert environment using a conductive AFM technique. It is shown that the π-stacked B-DNA structure is conserved on depositing the DNA. As a result, currents in the nanoampere range were obtained for voltages ranging between ±1 V. These experimental results are supported by a theoretical model that suggests that a multistep hopping mechanism between delocalized domains is responsible for the long-range current flow through this specific type of DNA. | Notes: | Jimenez-Monroy, KL (reprint author), Hasselt Univ, IMO IMOMEC, Campus Diepenbeek,Wetenschapspk 1, B-3590 Diepenbeek, Belgium. jimenezmonroy.kathia@gmail.com; n.renaud@tudelft.nl | Document URI: | http://hdl.handle.net/1942/23469 | ISSN: | 1089-5639 | e-ISSN: | 1520-5215 | DOI: | 10.1021/acs.jpca.7b00348 | ISI #: | 000394482500003 | Rights: | This is an open access article published under a Creative Commons Non-Commercial No Derivative Works (CC-BY-NC-ND) Attribution License, which permits copying and redistribution of the article, and creation of adaptations, all for non-commercial purposes. | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2018 |
