Determination of the authenticity of a drink as well as the existence or amount of its ethanol content is very important. Herein, silver nanoprisms were successfully used for the discrimination of different water-ethanol mixtures. The nanoparticles were characterized transmission electron microscopy (TEM) and UV-vis spectrophotometry. Moreover, using the color profile of the array, a reliable relationship was established for the determination of ethanol content in water-ethanol mixtures. Silver nanoprisms were prepared a green procedure using extracts of walnut peel, onion and red berry in the presence and absence of sodium citrate. The color variation of the prepared silver nanoprisms was used for discrimination. The RGB color indices of the sensor array were organized in matrices and processed principal component analysis (PCA) for discrimination and clustering.
确定饮品的真伪以及其乙醇含量的存在与否或含量多少非常重要。在此，银纳米棱晶成功用于区分不同的水 - 乙醇混合物。通过透射电子显微镜（TEM）和紫外 - 可见分光光度法对纳米颗粒进行了表征。此外，利用阵列的颜色特征，建立了一种可靠的关系用于测定水 - 乙醇混合物中的乙醇含量。银纳米棱晶采用绿色工艺制备，使用核桃皮、洋葱和红浆果提取物，有无柠檬酸钠均可。制备的银纳米棱晶的颜色变化用于鉴别。传感器阵列的RGB颜色指数被整理成矩阵，并通过主成分分析（PCA）进行处理以进行鉴别和聚类。
