 DESCRIPTION (provided by applicant): This project leverages new collaborations between biomedical and engineering investigators to develop new methods for the sorting and isolation of immune cells, where the precise trajectory of individual cells are controlled and sorted on a chip analogous to the way electrons are controlled inside computer circuits. This set of tools allows for fundamentally new methods to study phenotype, genotype, and the morphology of single or pairs of single cells, over extended periods of time with precision that is unparalleled by existing techniques, such as flow cytometry and flow cell sorting. The overall stated aims of this research are to develop the engineering platform and demonstrate a biological application for a lab-on-a-chip device that can analyze thousands of single cells over long durations, exposure to multiple stimuli, and enable the extraction of individual, high-value, cells for furthe immunological analyses (RT-PCR, clonal expansion, etc.). We aim to 1) design and fabricate a lab-on-chip assay optimized for biological applications, 2) optimize the assay for biological applications, and 3) use this novel assay to study early cellular events in the disruption of HIV latency.

 描述（由申请人提供）：该项目利用生物医学和工程研究人员之间的新合作来开发用于免疫细胞分选和分离的新方法，其中单个细胞的精确轨迹在芯片上被控制和分选，类似于电子在计算机电路内被控制的方式。这套工具允许从根本上新的方法来研究表型，基因型，和单细胞或单细胞对的形态，在较长的时间内，精确度是无与伦比的现有技术，如流式细胞术和流式细胞分选。这项研究的总体目标是开发工程平台，并展示芯片实验室设备的生物学应用，该设备可以在长时间内分析数千个单细胞，暴露于多种刺激，并能够提取个体，高价值的细胞用于进一步的免疫学分析（RT-PCR，克隆扩增等）。我们的目标是：1）设计和制造一种针对生物学应用优化的芯片实验室检测方法，2）优化生物学应用的检测方法，3）使用这种新的检测方法来研究HIV潜伏期中断中的早期细胞事件。
