C 2013 American Chemical Society Macroscopic Highly Aligned DNA Nanowires Created by Controlled Evaporative Self-Assembly

NA is a promising construction material for producing well-defined nanostructures for electronic, mag-netic, optoelectronic, and sensory applica-tions. In particular, DNA nanowires produced by stretching DNA permit the physical map-ping and diagnosis of diseases,1 and can also serve asunique templatesdue to their aligned structure and rich chemical functionality2 for potential use in superconducting nanowires,3 waveguides,4 photodetection,5,6 field-effect transistor,7 nanophotonic switch,8 bio-sensors,9 nanowire transistor,10 thermal switch,11 logic device,12 etc. Notably, the prerequisite for most of these application
