Guanine crystals are present in the skin of a wide range of animals, providing vivid structural colors. Growing guanine crystals with similar optical properties in vitro is a still unmet challenge. Using guanine‐based peptide nucleic acid monomers, a reflective array of self‐assembled spheres is developed by E. Gazit and co‐workers, as described on page 2195. The guanine‐based supramolecular structure changes color, similar to the spectral change mechanism employed by chameleons.
