“…In recent years, there has been an increasing demand for high-throughput and massively parallel fabrication strategies for the creation of large-area, highly ordered and periodic nanostructures, since these nanostructures have found a wide range of applications in many devices such as light emitting diodes (LEDs) [1], fuel cells [2], high dense data storage [3], photodetectors [4], surface plasmonics [5], photonic crystals [6,7], nanofiltration [8], artificial cells [9], metal-insulator-metal [10], and multi-functionalized DNA arrays [11]. The implementation of highly ordered nanostructure can be attained by a number of fabrication techniques including immersion lithography [12], electron-beam lithography [13,14], focused-ion-beam lithography [15,16], X-ray lithography [17,18], DUV lithography [19], UV interference lithography [20], nanoimprint lithography [21,22], near-field scanning optical microscope lithography [23], and other so-called top-down methods.…”

To learn from nature for the rational design of optical devices, the chemical and physical aspects of textures of these natural organisms should be systematically unraveled. Then the basic mechanisms as to how these structural units interact with light must be understood in depth. Finally, whether these morphologies can be fabricated by templating methods, by the current top-down methods, or by selfassembly methods should be well assessed. Up to now, biotemplating methods that take advantage of the physicochemical interactions between organic skeletons and the target solid-state materials are broadly adopted, as they are both cost and time effective. Many natural organisms have been successfully used as biotemplates to fabricate artifi cial photonic materials, including butterfl y wings, [20][21][22][23] beetles, [ 24,25 ] plant leaves, [ 26,27 ] and diatoms. [ 28,29 ] The biotemplating method can not only maintain the morphology of the natural organism, but also mimic the optical functions of the biological species. In addition, a wide range of high-quality photonic nanostructures have been fabricated using top-down methods, such as direct laser writing, photoetching, soft-lithography, and electron beam lithography. [ 10,[30][31][32] Some self-assembly systems can also provide us with novel photonic templates for the fabrication of functional materials, such as the opal structure selfassembled by polymer or silica spheres, [ 33,34 ] and some cubic phases self-assembled in block copolymer systems. [35][36][37] Inspired by natural organisms, researchers have achieved great progress in developing photonic materials in recent years. Many natural species, including birds, [ 3,38,39 ] insects (especially Lepidoptera and beetles), [ 3,[40][41][42][43] plants, [ 44,45 ] and aquatic organisms, [ 29,46 ] have a striking appearance with vivid structural colors originating from elaborate photonic crystals (PCs). PCs are periodic photonic nanostructures at the visible light wavelength scale that can affect the propagation of light. Inspired by these vivid structural colors, optical materials with photonic microstructures and brilliant color have been fabricated with applications in areas covering the cosmetics industry, [ 47 ] textile industry, [ 48 ] printing, [ 49 ] displays, [ 16 ] and security labeling. [ 5 ] As we know, structural colors originate from the interaction of light with various elaborate photonic structures, and are mainly determined by three structural parameters: the refractive index ratio, the volume fraction, and the unit cell size. [ 24 ] For certain optical systems, the photonic structural parameters can be tuned by exerting external fi elds to which the compositions are responsive, such as pH, [ 22,50 ] electromagnetic fi elds, [ 23,51 ] thermal fi elds, [ 52,53 ] gases, [ 54,55 ] and so on.

The well-organized chitosan film on mica surface has drawn wide attention for its potential applications and studies on the process of self-assembly. In this article, atomic force microscopy was used to investigate the ultrastructure of the self-assembly of chitosan molecules with calcium ions in different concentrations. It was showed that calcium ions might affect the selfassembly of chitosan to a certain extent, and chitosan molecules gathered from fibrils to circular, and finally formed to film with the increasing concentration of calcium ions. Further, the formation mechanism of Ca(II)chitosan conjugates was adapted to explain the effects of calcium ions on the self-assembly of chitosan. These results and the related analysis would be valuable for guiding the pattern of chitosan self-assembly with a potential application in food packaging science and engineering. ARTICLE HISTORY
