Biomimetic and bio‐inspired membranes draw great attention and generate extensive efforts to solve environmental, health, and energy issues. In this field, track‐etched membranes present the advantage to be tuned from a single pore to a large‐scale multipore membrane. On one hand, from the large‐scale membrane to a single nanopore, the research becomes more fundamental, meticulous, and quantitative to describe concrete processes inside confined spaces. This allows understanding the role of the surface phenomena and nanoscale effects. On the other hand, working from a single pore to a multipore membrane allows perfect control of the membrane properties. This ensures a promising ability for upscale from the lab findings to applications. In this review, a global insight on the track‐etched nanopore/membrane is taken through presentation of fabrication and functionalization methods, transport properties, and the related applications. By functionalization, track‐etched nanopores can be used to understand ion transport under confined spaces with high aspect ratio, to analyze single molecules, to design stimuli‐responsive membranes, and to generate energy from salinity gradient and light.

刻蚀的纳米孔/膜：从基础到应用

仿生膜和受生物启发的膜引起了广泛关注，并为解决环境，健康和能源问题做出了广泛努力。在该领域，轨迹蚀刻膜具有从单孔调整为大型多孔膜的优势。一方面，从大型膜到单个纳米孔，这项研究变得更加基础，细致和定量，以描述密闭空间内的具体过程。这样可以了解表面现象和纳米尺度效应的作用。另一方面，从单孔到多孔膜的工作可以完美控制膜的性能。这确保了从实验室发现到应用的升级前景。在这篇评论中通过介绍制造和功能化方法，传输性质以及相关应用，可以获得对轨迹蚀刻纳米孔/膜的全球性见解。通过功能化，可以使用径迹蚀刻的纳米孔来了解高纵横比的密闭空间内的离子迁移，分析单个分子，设计刺激响应膜并从盐度梯度和光中产生能量。
