transmission electron microscopy (TEM) image

The transmission electron microscopy (TEM) image (a) shows a cross section of ribbonfish skin (scale bar, 5 mm). Figure (b) illustrates a superlattice of cytoplasm and guanine crystal layers matching the dashed red line in (a). Figure (c) illustrate a five-stage Cantor bar. Changes introduced into the fractal lead to a pattern that resembles the superlattice in Figure (b).
