含有活蛋白石的光合作用藻细胞内细胞器对环境光照做出动态反应。天然光子晶体在不同的自然系统中具有很强的选择波长反射率。我们证明了在藻类Cystoseira Tamariscifolia中，由光合作用细胞内的脂类形成的细胞内蛋白石状光子晶体产生了鲜艳的结构颜色。乳白小泡的反射率对环境光照有动态响应。结构色存在于适应低光的样品中，而较高的光照水平会导致结构色缓慢消失，从而最终完全消失。一旦回到弱光条件下，这种颜色就会重新出现。我们的结果表明，这些复杂的细胞内天然光子晶体对环境条件做出了响应，可逆地改变了它们的堆积结构，并有可能操纵光来发挥视觉信号以外的作用。
A photosynthetic algal intracellular organelle containing a living opal responds dynamically to environmental illumination. Natural photonic crystals are responsible for strong reflectance at selective wavelengths in different natural systems. We demonstrate that intracellular opal-like photonic crystals formed from lipids within photosynthetic cells produce vivid structural color in the alga Cystoseira tamariscifolia. The reflectance of the opaline vesicles is dynamically responsive to environmental illumination. The structural color is present in low light–adapted samples, whereas higher light levels produce a slow disappearance of the structural color such that it eventually vanishes completely. Once returned to low-light conditions, the color re-emerges. Our results suggest that these complex intracellular natural photonic crystals are responsive to environmental conditions, changing their packing structure reversibly, and have the potential to manipulate light for roles beyond visual signaling.
