生物发色团黄瘤素 (Xa) 导致头足类动物和节肢动物呈现黄色、红色和棕色。在许多情况下，Xa 也作为超分子纳米结构的一部分或与其耦合存在，其功能尚未得到充分探索。为了研究这些结构元素如何影响这些天然发色团的感知颜色，制造了含有与 100 nm 聚苯乙烯纳米颗粒 (PS100-XA) 化学偶联的 Xa 的非晶光子组件，并将其与不同尺寸的纯聚苯乙烯 (PS) 纳米颗粒混合。观察到的结构颜色由这些双分散胶体组件组成，这些胶体组件通过 PS 纳米粒子的粒径、PS100-XA 的浓度、局部环境和组装方法进行调整。在所有情况下，添加 PS100-XA 都可以通过增加光吸收同时最大限度地减少不相干光散射来调节所得组件的色调和对比度。总而言之，结果证明了像 Xa 这样的生物色素如何增强常见光子组件中的颜色强度和颜色多样性。
The biological chromophore xanthommatin (Xa) contributes to the yellow, red, and brown colors and hues in cephalopods and arthropods. In many cases, Xa is also present as part of or coupled to supramolecular nanostructures, whose function has yet to be fully explored. To investigate how such structural elements impact the perceived color of these natural chromophores, amorphous photonic assemblies containing Xa chemically coupled to 100 nm polystyrene nanoparticles (PS100‐XA) are fabricated, and blended with pure polystyrene (PS) nanoparticles of varying sizes. Structural colors are observed comprising these bidispersed colloidal assemblies that are tuned by the particle size of PS nanoparticles, the concentration of PS100‐XA, the local environment, and the method of assembly. In all cases, the addition of PS100‐XA regulates the color hue and contrast of the resultant assemblies by increasing light absorption while minimizing incoherent light scattering. Taken together, the results demonstrate how biochromes like Xa can enhance the color intensity and the diversity in colors present in common photonic assemblies.
