以硫代丙酸修饰的碲化镉、谷胱甘肽修饰的碲化镉、聚甲基丙烯酸修饰的银纳米团簇、牛血清白蛋白修饰的金纳米团簇、罗丹明衍生物和钙黄绿素蓝为荧光指示剂，设计了一种交叉反应传感器阵列，用于检测7种重金属离子(Ag+、Hg2+、Pb2+、Cu2+、Cr3+、Mn2+和Cd2+)。测试了传感器阵列在不同pH溶液中对不同重金属离子的分辨能力，并对结果进行了线性判别分析。结果表明，该传感器阵列可以对所选择的重金属离子进行定性分析。在已知和未知样品的识别中也对该阵列的性能进行了评估，初步结果表明所设计的传感器检测方法具有良好的实用性。(C)2014爱思唯尔B.V.保留所有权利。
A cross-reactive sensor array using mercaptopropionic acid modified cadmium telluride (CdTe), glutathione modified CdTe, poly(methacrylic acid) modified silver nanoclusters, bovine serum albumin modified gold nanoclusters, rhodamine derivative and calcein blue as fluorescent indicators has been designed for the detection of seven heavy metal ions (Ag+, Hg2+, Pb2+, Cu2+, Cr3+, Mn2+ and Cd2+). The discriminatory capacity of the sensor array to different heavy metal ions in different pH solutions has been tested and the results have been analyzed with linear discriminant analysis. Results showed that the sensor array could be used to qualitatively analyze the selected heavy metal ions. The array performance was also evaluated in the identification of known and unknown samples and the preliminary results suggested the promising practicability of the designed sensor assay.
