A flow-through electronic tongue based on miniaturized ion-selective electrode array was used for the classification of the maize leaf samples (Zea mays) exposed to media containing Pb(II) ions. The system provided a good recognition of the extracts from the plant leaves treated with solutions of varying concentrations of Pb(NO(3))(2). Additionally, samples derived from specific segments of the maize leaf, representing different developmental stages of cells, were also discriminated. The presented results showed that the developed sensor array combined with Partial Least Squares-Discriminant Analysis (PLS-DA) technique allowed to recognize the plant samples on the basis of the changes in the ionic composition of the leaf homogenates.
基于微型离子选择性电极阵列的流通式电子舌用于对暴露于含 Pb(II)离子介质中的玉米叶片样品(Zea mays)进行分类。该系统能够很好地识别用不同浓度的 Pb(NO(3))(2)溶液处理的植物叶片提取物。此外,还可以区分来自玉米叶片特定部位的样本,这些样本代表了细胞的不同发育阶段。所呈现的结果表明,所开发的传感器阵列结合偏最小二乘判别分析(PLS-DA)技术,可以根据叶片匀浆离子组成的变化来识别植物样品。
