中文摘要: 禽流感等流行性疾病正日益威胁着人类生命健康安全,快捷有效的检测技术对控制病毒大范围传播至关重要。本项目基于微流控芯片技术,开发可同时对多样品多疾病进行并行酶联免疫吸附试验的便携式芯片系统。通过设计上下两层不同深度微通道,对免疫吸附微球在微流控芯片的反应室内定向堆集,从而避免使用复杂的微坝结构来拦截微球。利用交联微通道网络芯片、压应力控制阀和自动化的芯片操控台组成的微流控芯片系统,实现对携带不同抗原的聚苯乙烯微球的定向投放和多种生物样品及试剂的并行进样,达到对多生物样品的多病毒免疫分析。成功完成实验室内标准样品的分析后,该系统将应用于对禽流感各亚型病毒的实际样品分析。本微流控系统最大的特色是高速并行分析能力,而微流控芯片操控台的研制技术也将为开发便携式的微流控芯片疾病诊断系统奠定基础。本项目的顺利实施最终将可实现高效便捷的现场病毒检测,并为新发流行病提供方便快捷的研究工具。

英文摘要: Avian influenza and other epidemic diseases are threatening the health and safety of human, an efficient and effective detection technique to control a wide range of virus spread is essential. This project is based on a microfluidic technique, to develop a multi-sample multi-disease portable microfluidic system for parallel enzyme-linked immunosorbent assay. Microspheres of immunosorbent assay are introduced into microchannel and stacked in reaction chambers by design of an upper and a lower PDMS layer with different depths for the microchannels, thus avoiding the use of complex micro-bar to intercept the microspheres. The microfluidic system, which is consisting of cross-linked microchannel network chip, compressive stress valves and automated chip manipulation system, can directional stack the polystyrene microspheres carrying different antigens, sample a variety of biological samples and reagents, and realize multi-viral immune analysis of multiple biological samples. After successful demonstration of analyzing standard samples in the laboratory, this system will be applied to real sample analysis of the avian influenza virus. The most outstanding feature of this microfluidic system is high-speed parallel analysis capability, and the development of the microfluidic manipulation system will lay a foundation of
