Long, Monomolecular Guanine‐Based Nanowires

Abstract

Molecular nanowires for nanoelectronics may be built from guanine (G) tetrad building blocks. Spontaneous assembly of guanine-rich DNA sequences that form tetrads and further arrange into a tetrahelix structure produces long, continuous monomolecular G-wires (see Figure and cover), presumably G4-DNA, composed of single self-folded poly(G) strands of thousands of bases.
