论文摘要
固态膜中的纳米孔是能够探测纳米流体现象或可以充当单个分子传感器的工具。它们在过滤，脱盐或渗透发电方面也有多种应用。这些应用中的许多涉及化学或静水压力差异，它们对支撑膜和通过孔的离子传输作用。通过使用膜的侧面之间的压力差，以及一种交替的探头离子传输方法，我们研究了两个不同的物理现象：通过纳米孔在纳米孔的菌株测量以及由于孔隙侵入效应而导致的压力的离子电流重新配置的弹性变形以及离子电流的增长。
Nanopores in solid state membranes are a tool able to probe nanofluidic phenomena or can act as a single molecular sensor. They also have diverse applications in filtration, desalination or osmotic power generation. Many of these applications involve chemical, or hydrostatic pressure differences, which act on both the supporting membrane and the ion transport through the pore. By using pressure differences between the sides of the membrane, and an alternating current approach to probe ion transport, we investigate two distinct physical phenomena: the elastic deformation of the membrane through the measurment of strain at the nanopore, and the growth of ionic current rectification with pressure due to pore entrance effects.
