Direct Measurement of Electrical Transport Through G‐Quadruplex DNA with Mechanically Controllable Break Junction Electrodes

Abstract

Totally wired: The folding of G-quadruplexes leads to a stacking of the G-bases, which provide a relatively large conductance. Stretching these complexes results in changes to the resistance that are only slightly over a broad range of molecular lengths. G-quadruplexes can thus be seen as molecular wires with adjustable length.
