Structured color in nature is controlled by nano- and micro-structured interfaces giving rise to a photonic bandgap. This study presents a biomimetic optical material based on polymeric inverse opals that respond to enzyme activity. Polymer colloids provide a template in which acryloyl-functionalized poly(ethylene glycol) is integrated; dissolution of the colloids leads to a hydrogel inverse opal that can be lithographically patterned using transfer printing. Incorporating enzyme substrates within the voids provides a material that responds to the presence of proteases through a shift in the optical properties.

酶促反蛋白石水凝胶。

自然界中的结构色受纳米和微结构界面的控制，从而产生光子带隙。这项研究提出了一种仿生光学材料，其基于对酶活性有反应的聚合物反蛋白石。聚合物胶体提供了一个模板，其中整合了丙烯酰基官能化的聚乙二醇；胶体的溶解导致水凝胶反蛋白石，该蛋白石可以使用转移印刷进行光刻图案化。在空隙中掺入酶底物提供了一种通过光学性质的变化对蛋白酶的存在做出响应的物质。
