中文摘要: 癌症是威胁人类健康的重要原因之一,癌症早期诊断的发展受到广泛关注,其过程中涉及的大量目标物的筛选是制约早期诊断速度和效率的重要原因,因此发展高通量的多目标检测方法具有重要的科学意义。 本研究拟以光学编码的多目标检测方法为研究对象,主要内容包括:(1)建立程序性气动控制的多色量子点引入方法,构建微流控多内容物液滴形成芯片,以量子点为荧光团,建立微流控多色量子点编码系统,通过提高颜色编码数而指数性提高总编码数。(2)通过设计迪恩涡微结构实现微通道内微球的单列排序,利用回旋式检测通道和分光功能组件,搭建微流控多色荧光检测平台,建立高通量的微流控芯片多色量子点解码系统。(3)基于以上编码和解码系统,通过荧光免疫标记,建立多目标物检测体系,应用于血清样品中多种肿瘤标志物的连续检测。本项目拟建立的多色量子点编码和解码系统,可为癌症的早期诊断提供新的途径。

英文摘要: Since cancer is a significant threat to human health, the early diagnostics of cancer has attracted extensive attention. The screening of numerous targets has limited the speed and efficiency of cancer diagnostics. So it is highly desirable to develop a high-throughput screening method for multiple targets. The present project will focus on the optical encoding for multiple-target screening, including the following issues: (1) To establish a microfluidic multi-content droplet generator depending on the programmable and controllable multicolor quantum dot introducing mode. To develop a microfluidic multicolor quantum dot encoding system, based on the fluorophores of quantum dots. The total encoding number will rise exponentially by increasing the color encoding number. (2) To design Dean vortex microstructures to make the microspheres keep in a line in the micro-channel. To fabricate a microlfuidic multi-fluorescence detection platform and a high-throughput multicolor quantum dot decoding system according to a flexural detection microchannel and a spectra functional unit. (3) Based on the above encoding and decoding systems, to develop an immunofluorescent labeling multi-target detection method for performing the continuous detection of the multiple tumor markers in human serum. The presented multicolor quantum d
