摘要

本文介绍了一种具有独立功能结构的人眼可识别的刺激响应结构-彩色水凝胶化学传感器微阵列。该微阵列传感器的单个单元分为两个功能部分:刺激响应部分和结构颜色部分，可以对各种类型的目标分子进行可见颜色感知。为了证明我们的概念，我们制作了乙醇和Ag+离子响应微阵列传感器，其单元为100微米级，并观察了它们响应这些化学靶标的颜色变化。我们相信我们的传感器可以应用于持续的环境监测，如水质，并扩大材料的刺激响应结构彩色水凝胶传感器的范围。

Stimuli-Responsive Structural-Color Hydrogel Chemical Sensor Microarray with Separated Functional Structures

This paper describes an eye-recognizable stimuli-responsive structural-color hydrogel chemical sensor microarray having independent functional structures. Single unit of this microarrayed sensor is separated into two functional parts: a stimuli-responsive part and a structural-color part, enabling visible color sensing for various types of target molecules. In order to demonstrate our concept, we fabricated ethanol and Ag+ ions responsive microarrayed sensors with l00-µm-scale units and observed their color change in response to these chemical targets. We believe that our sensor could be applied to continuous environmental monitoring such as water quality, and widen the range of materials for stimuli responsive structural color hydrogel sensors.
