Abstract

Two forms of G4-DNA, with parallel and pairwise anti-parallel strands, are studied using atomic force microscopy. The directionality of the strands affects the molecules' structural properties (different height and length) and their electrical polarizability. Parallel G4-DNA is twice as polarizable as anti-parallel G4-DNA, suggesting it is a better electrical wire for bio-nanoelectronics.
