摘要

液滴单细胞包裹技术是实现单细胞研究的有效方法。采用负压作为驱动力包裹单细胞,不再需要常规实验中会引起细胞吸附和降低单细胞包裹率的进样器和管路。在细胞悬浮溶液中加入碘克沙醇溶液调整溶液密度,进一步改善细胞沉降问题。研究负压大小和T型沟道几何尺寸对液滴频率和体积的影响以及碘克沙醇调整溶液密度后对单细胞包裹率的影响。该微流控平台可实现稳定的单细胞包裹,并为单细胞分析提供有利工具。

Abstract

Negative pressures were used to generate droplets for single-cell encapsulations. Iodixanol was used to change the suspension solution densities in order to reduce the issue of cellular sedimentations. The effects of negative pressures and geometries of microfluidic T-channels on volumes and frequencies of generated droplets and the effects of iodixanol on the percentages of single-cell encapsulations were investigated and compared. This microfluidic platform may enable stable single-cell encapsulations, paving ways for single-cell analysis.
