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.
