“…Natural structure colors provide us with many wonderful inspirations to design and prepare the artificial structure colors. The colors by the self-assembled colloidal photonic crystals (CPCs) take the advantages of low cost, flexibility, and easy processability, which has shown great potential for new photonic materials and diverse practical applications, such as decorations, displays, storage, optical communication, and even quantum information systems ( Li et al., 2019a , 2019b ). The artificial CPCs can reflect brilliant colors due to the PBG, and they are able to be prepared into designable patterns over a large area ( Kim et al., 2009 ).…”

“…By patterning hydrophilic pinning points on hydrophobic surfaces, they also constructed the controllable 3D micro-CPCs patterns ( Wu et al., 2015 ). By printing MeOH/water on an inverse opal lattice, a patterning silk inverse opal strategy was developed for the generation of multispectral patterns ( Li et al., 2019a , 2019b ). Via the precise deposition, digitally designed photonic lattice and complex structural-color image were easily achieved ( Figures 9 E and 9F).…”

Summary Structural color attracts considerable scientific interests and industrial explorations in various fields for the eco-friendly, fade-resistant, and dynamic advantages. After the long-period evolution, nature has achieved the optimized color structures at various length scales, which has inspired people to learn and replicate them to improve the artificial structure color. In this review, we focus on the design of artificial structural colors based on colloidal particle assembly and summarize the functional bioinspired structure colors. We demonstrate the design principles of biomimetic structural colors via the precise structure engineering and typical bottom-up methods. Some main applications are outlined in the following chapter. Finally, we propose the existing challenges and promising prospects. This review is expected to introduce the recent design strategies about the artificial structure colors and provide the insights for its future development.

“…An alternative device configuration that circumvents the potential issue of photo‐bleaching of the gain medium when the CLC is photopolymerized is the defect‐mode structure 8–12. In this configuration a separate layer is formed for the gain medium that is sandwiched between two CLC layers ( Figure ).…”

Laser emission from a flexible defect‐mode structure consisting of two photopolymerized liquid crystal thin films separated by a dye‐doped polymethylmethacrylate defect layer is demonstrated. A simple and cost‐effective film transfer technique is used to fabricate the flexible laser and the corresponding laser emission characteristics, which shows single‐mode laser emission at λ = 582 nm, with an excitation threshold of Eth = 12.3 ± 0.5 µJ cm−2 per pulse and a slope efficiency of ηs = 6.0 ± 0.3%, are presented. The polarization state of the laser emission are also presented and are compared with the findings reported in the literature. Finally, laser‐beam steering is demonstrated up to 42° by subjecting the device to a mechanically induced deformation that creates a radius of curvature of 5 mm, which is of potential interest for conformable and wearable technology platforms.

“…As shown in Figure 3A, during Si etching, the use of patterned masks leads to patterned Si templates with micropillar arrays, producing ordered micropatterned PDMS templates followed with pat- structure. [26] The ordered structure of photonic crystals can enhance the fluorescence signal. When the reflection peaks are close or consistent with the excitation or emission wavelength of the fluorescent materials, they can enhance the fluorescence.…”

Flexible membranes (i.e., paper, cloth, and polydimethylsiloxane (PDMS)) have received extensive attention. The rapid development of flexible microfluidics and electronics and their integration calls for complex substrate structures to allow for multiple functions. Inspired by nature, meta-structured membranes (MSMs) as substrates for fabricating integrated microfluidics and electronics are presented. These flexible and freestanding MSMs are generated by the self-assembly of elastic plastic copolymer nanoparticle photonic crystals on micropatterned PDMS templates. The final MSMs constitute with integrated ordered micro-and nanostructures and exhibit spontaneous liquid transfer, fluorescence enhancement, and intimate skin contact. MSMs with designed patterns can be fabricated by assembling polymer nanoparticles on patterned molds; complicated and highly integrated electro-microfluidics are generated on one slice of MSMs by utilizing these patterns as microfluidic channels and electrocircuits. They can be used as chip-on-skin sensors for biochemical-physiological hybrid monitoring sensing of the human body and as organ chips for cell culture and metabolite analysis under drug treatment. Their excellent properties show their potential value in cross-scale sensing and have broad potential applications.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adfm.201906745. response and initiative manipulation on one single membrane substrate, which demands interdisciplinary integration. In fact, the combination of microfluidics and electronics on a single membrane has shown great potential in fabricating flexible smart devices such as wearable sensors (skin chips) and organ chips.Considerable attention and efforts have been devoted to fabricating membranes with functions such as super adherence, [4] vivid colors, [5] self-healing, [6] energy harvesting [7] based on micro/ nanostructures. However, the monotonous structure of current membranes limits their performance in flexible smart sensing devices. The construction of robust, ordered-structure membranes as flexible substrates with multiple excellent functions is still anticipated.Among many strategies improving the functionality of membranes, metamaterials or metastructures have widespread concerns. In the past decade, there have been increasing interests in metamaterials (structures) in scientific communities. [8] With the rapid development of materials science and physics, metamaterials are interdisciplinary subjects, including electronic engineering, condensed matter physics, microwave, optoelectronics, classical optics, materials science, semiconductor science, and nanotechnology. [9,10] Among many forms of metamaterials, highly ordered, micro-nano hybrid structures are beyond most striking styles. [11,12] Although there have been some attempts in this field, the high processing cost and complex processing process limit its full application in various fields.Nature provides excellent strategies for the re...
