我们提出了一种用于生物医学和环境监测的新型在线分析系统。为了提供特定的分析物检测，将带有功能化水凝胶涂层的化学传感器与粘度传感器集成在一个小型化的生物相容流变化学微系统中。该传感器已在不同浓度的乙醇和盐的水溶液中进行了校准和测试。研究表明，聚电解质嵌段共聚物涂层对有毒过渡金属离子具有选择性敏感性。(C)2007 Elsevier B.V.保留所有权利。
We propose a new type of on-line analytics system for biomedical and environmental monitoring. In order to provide the specific analyte detection, a chemical sensor with a functionalised hydrogel coating has been integrated together with a viscosity sensor in a miniaturized biocompatible rheochemical microsystem. The sensor has been calibrated and tested in aqueous solutions of alcohol and salts of different concentration. The selective sensitivity of the polyelectrolyte block-copolymer coating to toxic transition-metal ions has been demonstrated. (c) 2007 Elsevier B.V. All rights reserved.
