Crystal Motifs Polymer Peptoid (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption Researchers developed a colorized map (right) to show the distribution of different types of crystal structures (left) that they found in the polymer peptoid sample. The scale bar in the map image is 50 nanometers, or 50 billionths of a meter.
