由于光子晶体在光存储、加密、显示和传感等领域具有广阔的应用前景，利用图案化的光子晶体来产生设计合理的颜色响应材料已经引起了人们的极大兴趣。在这里，提出了一种基于喷墨打印的策略，用于非接触、快速和直接地产生任意图案的光子晶体。该战略是基于使用基于水的生物聚合物的蛋白石结构，这种结构可以通过在光子晶格上精确地沉积流体来以高分辨率进行重塑。由此产生的数字设计的光子晶格格式同时利用结构颜色和材料瞬变打开了信息编码的途径，并将光学、生物材料和环境界面的功能组合在一个设备中。
Patterning of photonic crystals to generate rationally designed color-responsive materials has drawn considerable interest because of promising applications in optical storage, encryption, display, and sensing. Here, an inkjet-printing based strategy is presented for noncontact, rapid, and direct approaches to generate arbitrarily patterned photonic crystals. The strategy is based on the use of water-soluble biopolymer-based opal structures that can be reformed with high resolution through precise deposition of fluids on the photonic crystal lattice. The resulting digitally designed photonic lattice formats simultaneously exploit structural color and material transience opening avenues for information encoding and combining functions of optics, biomaterials, and environmental interfaces in a single device.
