单细胞分析在生物医学研究和临床医学中具有重要意义,微流控芯片是实现单细胞分析的有效工具.为了实现单个细胞的高效捕获与实时观测,基于流体力学设计了一种单列环状微流控芯片.对捕获腔设计了4种不同尺寸(15,20,25,30μm)的后端通道.采用Fluent软件对单列环状微流控芯片进行速度流场分析.模拟结果表明:后端通道为15μm和20μm的微流控芯片粒子捕获效果最好.选用后端通道为20μm尺寸的微流控芯片,进行单个聚苯乙烯微粒的捕获实验,实验结果表明:单列环状微流控芯片的捕获粒子效率可达到91.67%,为后续细胞捕获与细胞培养提供了研究基础.
Single-row ring microfluidic chip for particle capture
Single cell analysis is of great significance in biomedical research and clinical medicine applications. Microfluidic chip is an effective tool for single cell analysis. In order to achieve efficient capture and real-time observation of single cell,a single-row ring microfluidic chip is designed based on fluid mechanics. Four different sizes(15,20,25,30μm)of back-end channels are designed for each capture chamber. Velocity flow field analysis of single-row ring microfluidic chip is carried out by fluent software. Simulation results show that the microfluidic chip with the back-end channel size of 15μm and 20μm can achieve the best capture effect. A microfluidic chip with a back-end channel of 20μm is used to capture single polystyrene particles. Experimental results show that the capture efficiency of single-row ring microfluidic chip can reach up to 91. 67%,which provides a research basis for subsequent cell capture and cell culture.
