Synthetic and biogenic guanine crystals have distinct morphologies. (A) A synthetic guanine crystal with a prismatic morphology, where the (100) crystallographic plane is the fastest growing direction. (B) A biogenic plate-like guanine crystal in a zebrafish eye. (C) Schematic illustration of both synthetic and biogenic crystals, where the (100) crystallographic plane is constructed from H-bonded molecular layers. (D) A zebrafish larva at 5 days post-fertilization contains guanine crystals in its eyes and skin. Insets show higher magnifications of the eye (cyan) and crystal-containing iridophores (pink). A and B are SEM micrographs and D shows incident light images. |
