在这项研究中，寻求三个主要目标：（a）通过结合“捕获元件”（由溶胶衍生基质上的α环糊精组成）和“检测元件”（由2,6-二氯醌氯亚胺和氢氧化钠组成作为缓冲剂和电解质）构建生物传感器，（b）使用光谱和显微镜对传感器进行物理表征，以及（c）通过电化学设施表征传感器性能。相应地，拉曼光谱和紫外可见光谱已被用作诊断工具来分析溶胶衍生苯酚传感器的客体相互作用。本研究的目标是将电化学和比色检测元件结合起来。预计这项研究为使用生物传感器进行“单一化学”双功能检测提供了可能性。我们使用这种双功能检测器来鉴定苯酚。该检测器基于溶胶衍生的胶体化学来生产检测和传感元件，其中检测本质上是比色检测和电化学检测。
In this study, three main objectives are sought: (a) construction of the biosensor by incorporation of a “capturing element” (consisting of alpha cyclodextrin on a sol-derived substrate) and a “detecting element” (consisting of 2,6-dichloro-quinonechloroimine and sodium hydroxide as buffer and electrolyte), (b) physical characterization of the sensor using spectroscopy and microscopy, and (c) sensor performance through electrochemical facility. Correspondingly, Raman spectroscopy and UV–vis spectroscopy have been applied as diagnostic tool to analyze guest–host interaction of the sol-derived phenol sensor. The goal of this study is the incorporation of both an electrochemical and colorimetric detecting elements. It is anticipated that this study provides a possibility of use of biosensor for “one chemical” dual-functional detection. We use this bi-functional detector in the identification of phenol. The detector is based upon sol-derived colloidal chemistry to produce detecting and sensing elements in which detection is colorimetric and also electrochemical in nature.
