TL;DR: A novel method to create photonic microgranules composed of glassy packing of silica particles and small fraction of carbon black nanoparticles, which show pronounced structural colors with low angle-dependency, thereby providing improved color contrast.

TL;DR: Three-dimensional flow-focusing geometry is advantageous for stably producing femto- to atto-liter droplets without the retraction problem of the dispersed phase fluid and it is demonstrated that the double emulsions can be used as morphological templates of ultrafine spherical silica capsules with controlled hierarchical pore networks via the evaporation-induced self-assembly (EISA) method.

TL;DR: In this paper, stable photonic structures created by using colloidal building blocks composed of an inorganic core and an organic shell are reported. But, complex fabrication procedures and low mechanical stability severely limit their practical uses.

TL;DR: In this paper, a single-step encapsulation technique was proposed to efficiently and precisely encapsulate a specific number of emulsion droplets in photocurable shell droplets, and these structures were then consolidated into multi-cored microcapsules with structural and mechanical stability through in situ photopolymerization of the shell in a continuous mode.
