The strong lines in this image echo the sinuous shape of double-stranded DNA. Imaging such a small structure—forty thousand times narrower than a single human hair—requires a very specialized instrument. This image was created as an early test of a new atomic force microscope, which uses a minuscule and precisely controlled physical probe to construct images of structures that were previously beyond the reach of scientific instrumentation.
