A multi-metal ion sensor for analysis of environmental water

一种用于环境水分析的多金属离子传感器。本研究项目的目的是在单芯片上开发一种电化学传感器阵列，用于检测废水样品中的几种重金属。阵列中的每个电极将被不同的金属结合肽配体修饰；产生给定金属离子的特征响应模式。将传感器响应反卷积成单个金属的响应模式将使用采用人工神经网络和其他多元技术的模式识别软件来实现。多分析物传感器的成功开发将允许在现场对环境重要的金属离子进行快速监测。

A multi-metal ion sensor for analysis of environmental water. The aim of this research project is to develop an electrochemical sensor array on a single chip for the detection of several heavy metals in wastewater samples. Each electrode in the array will be modified with a different metal-binding peptide ligand; resulting in a characteristic response pattern for a given metal ion. Deconvolution of the sensor response into the response patterns of the individual metals will be achieved using pattern recognition software employing artificial neural networks and other multivariate techniques. Successful development of the multi-analyte sensor will allow the rapid monitoring of environmentally important metal ions in the field.
