Abstract
Chemical sensors have targeted various substances. Most sensors electrically amplify signals. Here, we propose a visual detection system that uses a hyperswollen lamellar phase and detects targets in a solution without electric amplification. Amphiphiles with an oligo(ethylene glycol) chain can catch alkali and alkaline earth metal ions and amplify to macroscopic birefringence.
摘要
化学传感器已针对各种物质。大多数传感器通过电方式放大信号。在此，我们提出一种视觉检测系统，该系统使用超溶胀层状相，无需电放大即可检测溶液中的目标物。带有聚乙二醇链的两亲物可以捕获碱金属和碱土金属离子，并放大至宏观双折射。
