Long, Monomolecular Guanine-Based Nanowires

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...

Description
Summary: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.
