is an herb with a good medicinal value whose main active ingredient is polysaccharide (BSP) in the tuber of . In this study, a polysaccharide-based semi-interpenetrating network hydrogel was constructed by introducing BSP into polyacrylamide (PAM) hydrogel. The introduction of the BSP chain no only maintains the excellent mechanical properties of PAM, but also endows it with good biocompatibility. By implanting the colloidal crystal array into the above hydrogels, we obtained a novel biomass-based photonic crystal with good stimulus responsiveness that is sensitive to volatile organic compounds (VOCs), especially alcohol vapor. In addition, due to the scavenging ability of BSP to hydroxyl radicals, the photonic crystal hydrogel also has a good response to hydrogen peroxide (H2O2).
是一种药用价值很高的草本植物，其主要活性成分是 根茎中的多糖 (BSP)。在本研究中，通过将 BSP 引入聚丙烯酰胺 (PAM) 水凝胶中构建了基于多糖的半互穿网络水凝胶。BSP 链的引入不仅保持了 PAM 的优异机械性能，而且赋予其良好的生物相容性。通过将胶体晶体阵列植入上述水凝胶中，我们获得了一种新型的基于生物质的光子晶体，它对挥发性有机化合物 (VOC) ，特别是酒精蒸气具有良好的刺激响应性。此外，由于 BSP 对羟基自由基的清除能力，光子晶体水凝胶对过氧化氢 (H2O2) 也有很好的响应。
