“…Structural colors, i.e., colors originating from interactions of light and nanostructured materials, are incredibly widespread in living organisms. [ 1–3 ] From bacteria, [ 4 ] to plants, [ 5,6 ] insects, [ 7–13 ] and larger animals. [ 14–16 ] Different organisms produce bright colorations with various mechanisms and for diverse functions.…”

Pachyrhynchus sarcitis weevils are flightless weevils characterized by colored patches of scales on their dark elytra. The vivid colors of such patches result from the reflection of differently oriented 3D photonic crystals within their scales. The results show that hybrid P. sarcitis, the first filial generation of two P. sarcitis populations from Lanyu Island (Taiwan) and Babuyan Island (Philippines), mixes the color of its ancestors by tuning the photonic structure in its scales. A careful spectroscopical and anatomical analysis of the weevils in the phylogeny reveals the hereditary characteristics of the photonic crystals within their scales in terms of lattice constant, orientation and domain size. Monitoring how structural coloration is inherited by offspring highlights the versatility of photonic structures to completely redesign the optical response of living organisms. Such finding sheds light onto the evolution and development mechanisms of structural coloration in Pachyrhynchus weevils and provides inspiration for the design of visual appearance in artificial photonic materials.

“…36,50,74,75 Many aspects of disorder can be characterised using a statistical approach relying on measurements of physical features, for example: the distances between scattering centres, their sizes and shapes (e.g., number of sides or ellipticity), or their orientations, radial distribution functions or structure factors. 32,[52][53][54][76][77][78] In this paper, we suggest that the distributions of these measured quantities represent a useful measure of the extent of a system's disorder. For some systems, a measure of structural entropy has been dened.…”

“…Structural color has captured the fascination of optical researchers through numerous observations throughout history, both in naturally occurring structures and in the animal world (1)(2)(3). Plants have also evolved structural colors to fulfill a variety of functions (4-7): Structurally colored leaves (8)(9)(10), flowers (11,12), and fruits (4,5,13,14) are used by plants to regulate light harvesting (8,(15)(16)(17) and attract pollinators (6,7), while they are also believed to promote seed dispersal (4,5).…”

Photonic paper: Multiscale assembly of reflective cellulose sheets in Lunaria annua

Bright, iridescent colors observed in nature are often caused by light interference within nanoscale periodic lattices, inspiring numerous strategies for coloration devoid of inorganic pigments. Here, we describe and characterize the septum of the Lunaria annua plant that generates large (multicentimeter), freestanding iridescent sheets, with distinctive silvery-white reflective appearance. This originates from the thin-film assembly of cellulose fibers in the cells of the septum that induce thin-film interference–like colors at the microscale, thus accounting for the structure’s overall silvery-white reflectance at the macroscale. These cells further assemble into two thin layers, resulting in a mechanically robust, iridescent septum, which is also significantly light due to its high air porosity (>70%) arising from the cells’ hollow-core structure. This combination of hierarchical structure comprising mechanical and optical function can inspire technological classes of devices and interfaces based on robust, light, and spectrally responsive natural substrates.
