Hydrogen bonds are ubiquitous—and universally important—in chemistry. They give water its unique properties, speed or slow reactions, and hold together the three-dimensional shapes of DNA, proteins, and other supramolecular structures. But chemists have never actually seen them.

Now, with high-resolution atomic force microscopy (AFM), they have (Science 2013, DOI: 10.1126/science.1242603). The stunning images should enhance understanding of hydrogen bonds’ hitherto elusive properties.

AFM has produced . . .
