摘要

现有微流控等液滴单细胞包裹技术通常用来包裹平均粒径约10

m左右的小尺度细胞

存在着细胞包裹率不高和存活率较低的问题。考虑到微流体脉冲驱动技术能够实现油相中水相微液喷射且能精确控制微液滴的尺寸大小

本文提出了基于微流体脉冲惯性力驱动的虾卵细胞液滴包裹方法。搭建了基于微流体脉冲惯性力驱动的大尺度细胞(虾卵细胞)液滴单细胞包裹的实验装置

研究了微流体驱动参数对水相微液滴大小和单细胞包裹率的影响规律

通过调整微喷嘴尺寸和驱动电压

在油相中获得了直径为70~180

m的水相微液滴;实现了微喷嘴内虾卵细胞在沿微喷嘴轴线方向上不同位置处的规则排列

完成了1、2、3个或多个虾卵细胞的单液滴包裹

单细胞包裹率可达40%。本文的研究结果也可为大尺度细胞的液滴包裹方法提供参考。

Abstract

The existing droplet-based single cell encapsulation technology controlled by micro-fluidics is usually used to encapsulate micro cells with the scale of 10 micrometer and it shows disadvantages of low single cell encapsulating rates and low survival rates. In consideration of the microfluidic pulse driving technology can produce aqueous phase droplets in an oil phase environment and can precisely control the droplet size

this paper proposes a droplet-based encapsulating method of shrimp oocyte actuated by microfluidic pulse inertia force and establishes an experiment device for encapsulating large scale cells into single micro droplet. It researches the influence of microfluidic driving parameters on the droplet size and single cell encapsulating rate. By adjusting the size of a micro-nozzle and driving voltage

the aqueous phase micro droplet with a diameter of 70-180

m is obtained

and the regular arrangement of shrimp oocyte in the micro-nozzle is implemented in different locations on the axis direction of the nozzle arrangement. A single droplet randomly encapsulated with one

two

three or four cells is realized. The single cell encapsulating rate has reached by 40%. The results can provide references for larger scale cell encapsulation method.
