本文以枯草芽孢杆菌为例, 对单个细菌细胞谱系的微流体分析方法进行了研究。该方法克服了传统分析方法在微生物学中的不足, 允许在严格控制和均匀生长条件下观察几百个细胞世代。

这种微流体实验装置的总体目标是能够在恒定、高度受控的环境条件下长期观察单个细菌细胞。这种方法可以帮助回答细菌生理学领域的关键问题,例如单个细胞对压力的长期反应模式是什么,或者群体中的异质表型如何随时间变化。这项技术的主要优点是,我们可以在恒定、均匀和高度受控的环境条件下观察单个细胞谱系数十代甚至数百代。

根据文本方案制备 PDMS 聚合物后,将硅胶母版放在聚苯乙烯培养皿中的一块未破损的铝箔上。将脱气的 PDMS 混合物倒在母版上,深度约为 5 毫米。然后将培养皿脱气至少 10 分钟。
