摘要

我们介绍了一种微/纳米流体平台，可以全面分析和控制通过纳米通道网络的扩散渗透(DO)驱动的离子传输。纳米通道网络是通过纳米颗粒的自组装形成膜(即自组装颗粒膜，SAPM)在微流控通道中制备的。这种制造方法允许使用各种不同的纳米颗粒，从而有可能调节纳米通道网络的材料特性。利用该平台，我们借助温度开关器件(TSD)分析了不同浓度电解质溶液对do驱动离子输运的热效应。

Comprehensive Analysis and Control of Diffusioosmosis-Driven Ionic Transport Through Interconnected Nanoporous Membranes

We introduce a micro-/nanofluidic platform enabling the comprehensive analysis and control of diffusioosmosis (DO)-driven ionic transport through a nanochannel network. The nanochannel network is fabricated in the microfluidic channel by forming a membrane via the self-assembly of nanoparticles (i.e., self-assembled particle membrane, SAPM). This fabrication method allows to use various and different nanoparticles so that it is possible to modulate the material properties of the nanochannel network. Using the platform, we analyze the thermal effect on DO-driven ionic transport with various concentrations of electrolyte solutions with the aid of a temperature switching device (TSD).
