In recent years, several new methods have been developed to precisely manipulate small particles using optical, electric, acoustic, magnetic, or fluidic fields. Automated fluidic trapping has emerged as a particularly powerful method to control colloidal particles, cells, or single polymers using only fluid flow. Here, we discuss recent advances in the automation of particle manipulation, focusing on flow-based and electric field-based methods. Broadly, automated flow control enables the precise manipulation of multiple freely suspended particles using gentle flow, thereby enabling new directions in chemical and biological systems.

粒子处理的自动化和流量控制

近年来，已开发出几种新方法来利用光，电场，声，磁场或流体场精确地操纵小颗粒。自动化流体捕集已成为一种仅使用流体流来控制胶体颗粒，细胞或单一聚合物的强大方法。在这里，我们讨论粒子处理自动化的最新进展，重点放在基于流和基于电场的方法上。广义上讲，自动流量控制可以使用柔和的流量精确地控制多个自由悬浮的颗粒，从而为化学和生物系统提供新的方向。
