So far all visual and instrument-free methods have been based on a color change. However, colorimetric assays cannot be used by blind or color-blind people. Here we introduce a liquid-to-gel transition as a general output platform. The signal output (a piece of gel) can be unambiguously distinguished from liquid both visually and by touch. This approach promises to contribute to the development of an accessible environment for visually impaired persons.
到目前为止，所有无需视觉和仪器的方法都基于颜色变化。然而，比色分析不能供盲人或色盲者使用。在此，我们引入液-凝胶转变作为一种通用的输出平台。信号输出（一块凝胶）在视觉上和通过触摸都能与液体明确区分开来。这种方法有望为视障人士营造无障碍环境做出贡献。
