Caffeic acid (CA), as a natural plant-derived polyphenol, has been widely used in surface coating technology in recent years due to its excellent properties. In this work, caffeic acid was introduced into the preparation of photonic band gap materials. By controlling the variables, a reasonable preparation method of polystyrene (PS) @polycaffeic (PCA)–Cu(II) core–shell microspheres was achieved: 1 mmol L−1 cupric chloride anhydrous (CuCl2), 3 mmol L−1 sodium perborate tetrahydrate (NaBO3·4H2O), 2 mmol L−1 CA and 2 g L−1 polystyrene (PS) were reacted at 50 °C for 10 min to prepare PS@PCA–Cu(II) core–shell microspheres through rapid oxidative polymerization of CA coated PS of different particle diameters. The amorphous photonic crystal structure was self-assembled through thermal assisted-gravity sedimentation, resulting in structural color nanomaterials with soft and uniform color, no angle dependence, stable mechanical fastness and excellent UV resistance.

Aquatic viruses cause devastating diseases in aquaculture, severely limiting production and resulting in significant economic losses. The giant salamander iridovirus (GSIV), a member of the genus Ranavirus , is the only virus reported to infect giant salamanders, posing a severe threat to the farming industry. Currently, there are no effective strategies available for its control. In this context, a reliable diagnostic tool for the rapid detection of GSIV is crucial to mitigate its impact. This study developed a nanobody-based immunoassay for the rapid and reliable detection of GSIV. GSIV was cultured and used to immunize an alpaca, A phage library with an original diversity of 1.89 × 10 8 PFU was established, and six nanobodies were identified after three rounds of panning. Among them, HC-2 exhibited superior performance and was used to develop a highly sensitive ELISA method employing streptavidin-PolyHRP (SA-PolyHRP) as a signal amplification strategy. The assay achieved a detection limit of 3.3 × 10 5 PFU/mL and demonstrated high specificity without cross-reactivity. Practical application was validated in infected giant salamander samples, underscoring its diagnostic potential. This work provides a robust tool for GSIV diagnosis and showcases the potential of nanobodies in advancing aquaculture diagnostics.

Decapod Iridescent Virus 1 (DIV1) leads to high mortality rates in shrimp farming, significantly impacting the aquaculture industry economically. Currently, there are no effective treatments for controlling DIV1 infections, and management primarily relies on preventative measures. Rapid and precise diagnosis of DIV1 is crucial. In this study, we identified two DNA enzymes, MCP-1 and MCP-8, that can specifically recognize DIV1 via in vitro selection. The detection limit of MCP-1 was 6.89 copies/μL of DIV1. We developed a DNAzyme-based “turn off” biosensor for quick detection of DIV1, which is both highly specific and sensitive, by integrating SYBR Green I to enhance the signal. The detection limit of biosensor could reach 2.01 copies/μL of DIV1. Compared to conventional detection methods, this sensor delivers results in 5 min without the need for complex procedures, greatly streamlining the detection process.

The artificial design of nano-submicron structures to fabricate amorphous photonic crystals (APCs) is an effective means of obtaining non-iridescent structural color. APCs show great potential for applications in various fields, such as coating, textile coloring, displays, anti-counterfeiting, etc. However, a sharp fall in the structural color saturation can result due to incoherent scattering. In this paper, a type of light-absorbing material, SiO2@Ag, is prepared via a redox method. Non-iridescent structural color films with excellent color visibility and color saturation can be constructed through the layer-by-layer self-assembly of SiO2@Ag and SiO2 microspheres. Due to the inherent property of absorbing incoherent scattering light by the Ag nanoparticles, better structural color is generated without changing the originally ordered structure of the APC itself. Furthermore, no redshift or blueshift is caused by SiO2@Ag, which helps to maintain the color consistency well. Thus, excellent structure stability and color visibility are shown for the new type of APC film fabricated here, which will provide innovative ideas for the design and fabrication of non-iridescent structural color materials.

Amorphous photonic structures with non-iridescent and highly-stable structural color were fabricated via a simple one-step spray-coating technique. With this strategy, the obtained films on textile substrates presented short-ordered and amorphous photonic structures (APSs) similar to the amorphous nanostructures of avian feathers. The structural color presented the same hue when viewed at different angles and could be well controlled by varying the diameters of the SiO2nanospheres. The prepared fabrics with structural color exhibited high color stability due to stability in both the assembled physical structure and the refractive index. The high stability of the assembled physical structure was attributed to the cementing effect of Poly(methylmethacrylate-butylacrylate) P(MMA-BA) existing between textile substrate and SiO2nanospheres and among SiO2nanospheres, while the high stability in the refractive index was contributed by the liquid-resistance achieved by both the surface roughness and the low-surface-energy of the as-sprayed APSs. With the resistances to external forces and liquid invasion, the non-iridescent brilliant structural color of the as-prepared fabrics could be kept steady. In this study, an approach of fabricating APSs with non-iridescent and stable structural color was established to enhance its potential application in structural coloration of textiles, and other color-related smart textiles.Keywords:amorphous photonic structures;structural color;non-iridescent;color stability;textile substrates

Structural coloration of fabrics and phase-change thermoregulation are innovative development trends in the textile field. However, the inevitable assembly process of structural colors and the leakage of phase change materials make it extremely difficult. Herein, smart fabrics featuring non-iridescent structural color, and thermoregulation are developed by one-step loading of photonic nanopigments and phase change materials (PCMs). The photonic nanopigments are hollow silica (H-SiO 2 ) nanospheres with disordered metasurfaces that display non-iridescent structural colors without assembly. The used PCMs are lauric acid (LA) with solid-liquid phase change performance, which adsorb onto the surface of the H-SiO 2 nanospheres and form hydrogen bond cross-linkages with the oxyanions on the H-SiO 2 nanospheres surface. Among them, waterborne acrylic resin serves as an adhesive to immobilize the H-SiO 2 nanospheres and a cross-linker to form hydrogen bonds with molten LA, preventing its leakage. The resultant smart fabrics exhibit durable color stability and can withstand damage from diverse physical and chemical environments. The melting and crystallization enthalpy possessed are 38.94 and 40.51 J g⁻¹ respectively, endowing the smart fabrics with excellent thermoregulatory capabilities. This study offers a new paradigm for smart fabric advancement with structural color and thermoregulation.

Healthy, convenient, and aesthetic hair dyeing and styling are essential to fashion trends and personal–social interactions. Herein, we fabricate green, scalable, and aesthetic regenerated cellulose filaments (ACFs) with customizable iridescent colors, outstanding mechanical properties, and water-triggered moldability for convenient and fashionable artificial hairdressing. The fabrication of ACFs involves cellulose dissolution, cross-linking, wet-spinning, and nanostructured orientation. Notably, the cross-linking strategy endows the ACFs with significantly weakened internal stress, confirmed by monitoring the offset of the C–O–C group in the cellulose molecular chain with Raman imaging, which ensures a tailorable orientation of the nanostructure during wet stretching and tunable iridescent polarization colors. Interestingly, ACFs can be tailored for three-dimensional shaping through a facile water-triggered adjustable internal stress: temporary shaping with low-level internal stress in the wet state and permanent shaping with high-level internal stress in the dry state. The health, convenience, and green aesthetic filaments show great potential in personal wearables.

Responsive photonic crystals (PCs), which can adjust structural colors in response to external stimuli, show great potential applications in displays, sensors, wearable electronics, encryption, and anticounterfeiting. In contrast, conventional structure-intrusive adjustment manners that external stimuli directly interact with the ordered arrays may lead to structural damage or longer response time. Here, a noninvasive adjustment of the structural colors of two-dimensional (2D) PCs (2D-PCs) is explored based upon diffraction theory. Sealed 2D-PCs and 2D inverse opal photonic crystal (IOPC) flexible devices are prepared. They are highly transparent in air but immediately exhibit intense viewing angle-dependent structural colors after being dipped in water. The mechanism of transparent-iridescent immediate transformation is explained by Bragg’s law. The design mechanism is examined by numerical simulation and spectral shifts in different external media. We demonstrate its applications in the fields of information encryption and anticounterfeiting by using the transparent-iridescent immediate transformation of sealed 2D-PC patterns and 2D IOPC free-standing films sealed on the product surface. Because of the strong contrast between transparency and intense iridescence, reversible and immediate transformation, and durability, sealed 2D-PCs and 2D IOPC flexible devices designed by the noninvasive adjustment strategy will lead to a variety of new applications in displays, sensors, wearable electronics, encryption, and anticounterfeiting.

Structural color films with high brightness, saturation and robust mechanical properties have been prepared by a two-step photopolymerization method using colloidal inks. The color saturation of the films could be controlled by the mass of the carbon black (CB) particles and polymerization time while the colors are closely related to the diameter of the CB@SiO 2 microspheres . The inks were prepared by dispersing CB@SiO 2 microspheres with black CB particles as the core and inorganic SiO 2 as the shell in poly(ethylene glycol diacrylate) (PEGDA) resins. The results of bending and rubbing tests showed that the addition of PEGDA prevented the formation of film cracks and enhanced mechanical properties without altering the original color. Structurally colored films were directly attached to a variety of substrates, including glass, metal, paper, and fabric. These colloidal inks have potential application in the fields of displays, paints, and other color-related fields.

Monodisperse colloidal particles have promising applications in electrophoretic displays with vivid colors, reversibility and low switching times. In this study, a facile, effective and large-scale strategy for preparing size-controlled Fe3O4@SiO2 particles is reported. Multiple Fe3O4 particles were synthesized by a modified solvothermal method using sodium citrate as a surface modifier with a binary solvent, and were then coated with a SiO2 layer to obtain a highly negatively charged surface via a modified Stöber method. Owing to the easily controlled sizes and sufficient surface charges, Fe3O4@SiO2 particles can be assembled into colloidal amorphous arrays with the balance of electrostatic repulsion and electrophoretic forces. The reflections cover wavelengths ranging from 802 to 453 nm, and were optimized by investigating the dependence of the particles on variables such as particle size, particle volume fraction, and electric field intensity. The large-scale preparation of electrically responsive Fe3O4@SiO2 particles facilitates an electrophoretic display with broad-range colors, showing the practical potential in industrial application.

Background Photonic actuator materials that change their color in response to stimuli are uniquely suited for analyte sensing and visual detection. However, the changing iridescence produced by conventional photonic crystal structures in hydrogel materials can seriously confuse optical readouts, thus limiting their widespread application. Results Here, we report novel visual urea sensors with angle-independent structural colors. The urease-modified hydrogels were constructed into amorphous photonic structures. Based on the urease catalytic action induced charge variation within the hydrogel matrix, it leads to the volume change and corresponding diffraction wavelength shift of the photonic hydrogel biosensors, thereby enabling the stable and repeatable detection of urea. The response range of the sensors to urea solution ranged from 0 to 80 mM, with a linear range of 1–10 mM and a detection limit of 0.36 mM. Significance The visual and label-free sensors with non-iridescent structural colors have great potential in various response fields that require stable colors and open up a new avenue for the development of biomedical sensing photonic devices.

Non-iridescent structural color films and pigments with novel enhanced microwave absorption characteristics are successfully fabricated at room temperature for the first time. The quasi-uniform magnetite nanoparticles (CV = 0.10 ∼ 0.20) with high refractive index (n = 2.42) and broad light absorption provide evident low-angle-independent property for the structural color pigments. More importantly, a universal technical protocol is developed for preparation of photonic crystals with inorganic nanoparticles, i.e., through designing of the binding strength between nanoparticles and mediated molecules, the slurry modulus is increased to 10 5 Pa, which effectively drives the nanoparticles to rapidly assemble into closely packed ordered arrays by our-designed powerful assembly technique. Additionally, the structural color materials are subjected as photonic crystal pigments (∼20 wt%) embedding in a transparent polymer matrix to form color coatings. Remarkably, the photonic crystal pigments exhibit strong magnetic coupling effect and enhanced microwave absorption performance due to the regular arrangement, with superior reflection loss (RL min ) values of −14.97 dB (increase by 65.8 % compared with randomized magnetic nanoparticles), and the effective absorption bandwidth (EAB) of 2.15 GHz. This new kind of photonic crystal pigment, combining visual color and radar wave absorption, provides a novel idea for developing of multi-wave-band high-performance stealth materials.
