We demonstrated Japanese rice wine (sake) tasting using a fluorescent chemosensor array comprising polythiophene-based chemosensors functionalized with pyridinium boronic acid. The chemosensors bound to the components of sake (i.e., glucose and pyruvate) and showed changes in fluorescence as a result. To achieve on-site analysis, the chemosensor microarray was fabricated on a glass chip, for which an image pattern was rapidly recorded by using a CCD camera equipped with color filters. For high throughput and accurate analysis, the collected datasets were analyzed using pattern recognition techniques, and we discriminated between four nondiluted sakes based on the cross-reactive response of the polythiophene-based chemosensors. Moreover, the facile chemosensor sensor array succeeded in predicting unknown concentrations of glucose and pyruvate in diluted sake, which revealed its usability for drinks analysis.

我们使用荧光化学传感器阵列展示了日本黄酒（清酒）的品尝，该阵列包括用吡啶鎓硼酸功能化的基于聚噻吩的化学传感器。化学传感器与清酒的成分（即葡萄糖和丙酮酸）结合，结果显示出荧光变化。为了实现现场分析，化学传感器微阵列被制造在玻璃芯片上，通过使用配备有滤色器的 CCD 相机快速记录图像图案。为了实现高通量和准确分析，使用模式识别技术分析收集到的数据集，我们根据基于聚噻吩的化学传感器的交叉反应响应区分四种未稀释的清酒。而且，
