Abstract

In this tutorial review aimed at researchers using nanofluidic devices, we summarize the current state of theoretical and experimental approaches to describing concentration polarization (CP) in hybrid microfluidic-nanofluidic systems. We also analyze experimental results for these systems and place them in the context of recent theoretical developments. We then extend the theory to explain the behavior of both positively and negatively charged, low-concentration, analyte species in systems with CP. We conclude by discussing several applications of CP in microfluidics.

摘要

在这个面向使用纳流控器件的研究人员的教程综述中，我们总结了当前描述混合微流控-纳流控系统中浓度极化（CP）的理论和实验方法的现状。我们还分析了这些系统的实验结果，并将它们置于最近理论发展的背景下。然后，我们将理论扩展到解释带 CP 的系统中带正电荷和带负电荷的、低浓度分析物的行为。最后，我们讨论了 CP 在微流控中的几个应用。
