High-contrast direct DNA image, TEM
High-contrast direct DNA image. Transmission electron micrograph (TEM) of the first high-contrast direct image of a bundle (fibre) of strands of DNA (deoxyribonucleic acid). This bundle is six DNA strands wrapped around a seventh. The inset at lower right shows the helical structure, with the red arrows pointing to the edges of the helix. The width of a DNA strand is 20 angstroms (2 nanometres), and the scale bar (bottom left) is 20 nanometres long. This image was obtained by a team led by Enzo di Fabrizio from the Department of Nanostructure, at the Italian Institute of Technology (IIT) in Genoa. The results were published in November 2012 in the journal Nanoletters, and in Nature in January 2013
