微流体涡辅助电平台的连续交付的多个分子进入相同的细胞群与精确,独立的剂量控制开发。该系统的大小基于靶细胞纯化步骤前电穿孔辅助以增强分子递送效率和处理的细胞活力。

该程序的总体目标是使用涡旋辅助微流体孔以顺序和剂量可控的方式高效地输送各种类型的具有生物学意义的分子,这是通过首先准备四个 50 毫升离心管来实现的,这些离心管分别包含带有细胞和生物分子的 DPBS 溶液,并将每个管连接到其各自的小瓶支架连接到气动流量控制系统。第二步是将每个小瓶的入口管插入嵌入 15 针电极的微流体装置中。接下来,细胞流入设备,在那里它们被困在电穿孔室中形成的微尺度漩涡中。

最后一步是立即对被困的细胞施加短电脉冲,然后将含有要输送到胞质溶胶中的生物分子的溶液注入。最终,从该工艺中获得的细胞可以被释放和收集用于下游分析。与现有方法相比,该技术的主要优点是所提出的技术能够以高效率和活力将受控量的多个分子依次递送到预先选择的相同细胞群中。
