This paper propounds an approach for the simultaneous analysis of colorless analytes using optical sensor arrays. On the basis of the equilibrium law, the principles of indicator displacement assay (IDA)–based sensor arrays that can be utilized for the efficient quantification of analytes in the mixture solutions through multivariate hard modeling approach are discussed in detail. According to these principles, two different sensor array systems are designed for the simultaneous analysis of the analytes with nonselective signal in the mixtures. Each sensor element of the designed sensor arrays consists of a single indicator and receptor but has different equilibrium environmental conditions.

用于混合物定量的指示剂位移测定传感器阵列的基于模型的描述

本文提出了一种使用光学传感器阵列同时分析无色分析物的方法。在平衡定律的基础上，详细讨论了基于指示剂位移分析 (IDA) 的传感器阵列的原理，这些传感器阵列可用于通过多元硬建模方法对混合物溶液中的分析物进行有效量化。根据这些原理，设计了两种不同的传感器阵列系统，用于同时分析混合物中具有非选择性信号的分析物。设计的传感器阵列的每个传感器元件由单个指示器和接收器组成，但具有不同的平衡环境条件。
