Biomedical engineer Yonggang Ke‘s “DNA origami” artwork appears on the cover of Nature Methods, as part of a celebration of the journal’s 10th anniversary. Ke designed self-assembling DNA strands that would form a cylinder and a ring structure, let them assemble, and obtained images with transmission electron microscopy. The height of the final image is 120 nanometers, smaller than the wavelengths of visible light and about the size of an influenza or HIV virion.
