Summary: Colloidal crystals are used to develop structural colors, and a new type of elastic photonic microcapsules has been designed using these crystals as building blocks. By microfluidically preparing water-in-oil-in-water double-emulsion templates, the microcapsules can achieve high quality structural colors on macroscopic surfaces.

Summary: In this study, a 3D printing platform for the assembly of colloidal particles of silica and carbon with programmable structural color is proposed. The printing parameters and ink composition are optimized to achieve objects with tunable structural color. Multimaterial printing is used to create complex-shaped objects with multiple structural colors, offering a new approach for mimicking structural color in natural systems.

Summary: In this study, monodispersed nanogels with high color saturation levels were synthesized by copolymerizing N-phenyl maleanilic acid (NPMA) and N-(1-naphthyl) maleamic acid (NNMA) with N-isopropylacrylamide (NIPAm). These nanogels can form colloidal crystals and exhibit structural color in aqueous solution. By introducing N-hydroxyethyl acrylamide and the crosslinker polyurethane acrylate (PUA), the embedded colloidal crystals show reversible thermal responsiveness, making them potential indicators for drug monitoring and biosensing applications.

Summary: Photonic crystals with rainbow structural colors have been successfully fabricated through centrifugation-assisted assembly of lignin nanoparticles. The centrifugation process serves to classify the nanoparticles and produce monodispersed layers, resulting in gradient colors. The dynamic rearrangement of the lignin nanoparticles during assembly into semi-closed structures is crucial for the formation of photonic crystals.

Summary: A facile method for building responsive photonic crystal patterns was developed, utilizing commercially printed patterns as masks to induce invisible patterns through wetting. The masked areas exhibit strong structural colors while the unmasked areas remain transparent, providing a unique and reversible wetting feature. This programmable printing technique is expected to be an environmentally friendly approach for scalable invisible optical anti-counterfeiting technology.

Summary: This paper reports a practical method for preparing elastomer-immobilized nonclose-packed colloidal photonic crystal films with various uniform Bragg reflection colors using one kind of gel-immobilized nonclose-packed colloidal photonic crystal film. The degree of swelling was controlled by the mixing ratio of the precursor solutions, enabling the facile preparation of elastomer-immobilized nonclose-packed colloidal photonic crystal films with various uniform colors via subsequent photopolymerization. The present preparation method can contribute to the development of practical applications of elastomer-immobilized tunable colloidal photonic crystals and sensors.

Summary: This article introduces a mechanochromic photonic fiber that can visually respond to external stimuli and is widely used in colorimetric sensing, smart display, and medical care. A fiber with a wide color shift range is prepared by coating elastic rubber containing silica particles onto spandex yarn. The obtained photonic fiber displays a structural color that can be controlled by adjusting the diameter and volume fraction of silica particles and achieves reversible color change in the visible range. These fibers have great potential in smart wearables, display textiles, and visual sensors.
