摘要
为实现微流控芯片的高精度分析,设计了一种基于虚拟仪器的微通道电渗流检测系统。介绍了电渗流测定的常用方法及其优缺点,基于电流监测法原理设计了微通道电渗流检测系统的硬件结构,采用LabVIEW软件开发了人—机界面。并在不同电场强度作用下,完成了微通道电渗流的测定。实验表明:该设计的检测系统能很好地满足微通道内部电渗流检测的需求。
To realize the analysis with high precision in microfluidie chips, a detection system of electroosmotie flow（EOF） in microchannels based on virtual instrument is presented. Conventional methods to detect the EOF and its characteristics are introduced. The hardware structure of the detection system based on current-monitoring method is built up, and the human-machine interface is developed by the LabVIEW. Measurement of EOF on microfluidic chip is achieved. Experiment results demonstrate that the proposed system can satisfy the requirement of the detection of EOF in microehannel.
