“…Figure 1c schematically shows the correlation of ν bulk and ν track . For better visibility, the scaling of the etch cone and the latent track is biased [61]. The etching of bulk material leads to a reduction of the foil thickness and a widening of the nanochannel perpendicular to the surface of the “etch-cone.” The removal of the track material with speed ν track is responsible for the breakthrough of the membrane.…”

Nature has inspired the fabrication of intelligent devices to meet the needs of the advanced community and better understand the imitation of biology. As a biomimetic nanodevice, nanochannels/nanopores aroused increasing interest because of their potential applications in nanofluidic fields. In this review, we have summarized some recent results mainly focused on the design and fabrication of one-dimensional nanochannels, which can be made of many materials, including polymers, inorganics, biotic materials, and composite materials. These nanochannels have some properties similar to biological channels, such as selectivity, voltage-dependent current fluctuations, ionic rectification current and ionic gating, etc. Therefore, they show great potential for the fields of biosensing, filtration, and energy conversions. These advances can not only help people to understand the living processes in nature, but also inspire scientists to develop novel nanodevices with better performance for mankind.

materials. For example, nanochannels fab ricated in elastic materials can respond to an applied pressure, [4] and conical nanochannels in poly(ethylene tereph thalate) (PET) membranes can respond to pH. [5] Thus, it is convenient to achieve simple responsive properties by directly using responsive materials to construct the nano channels. The second route is an indirect method, where functional molecules and materials are modified onto the inner surfaces of nanochannels. This method can change the physical and chemical properties of nanochannels to make the system more intelligent. [6] Smart bioinspired nano channels with different shapes and compositions have been fabri cated, and these nanochannels can respond to various stimuli, such as pH, [7] light, [8] temperature, [9] specific ions, [10] and mole cules. [11] Compared with their fragile biological counterparts, smart bioinspired nanochannels possess excellent mechanical robustness, controllable geometry, tunable surface properties, and good chemical stability. [12] These advantages make them useful for many potential applications, ranging from molecular filters to biosensors to energy conversion devices. [13] Smart bioinspired nanochannels not only provide a basic research platform to simulate the ion transport process in living bodies, but also boost the generation of energy conver sion devices. In nature, ion channels can be used as switches to regulate mass transport and energy conversion. Learning from nature, numerous energy conversion systems based on artificial ion channels have been devised, [14] which are of great significance for the development of sustainable energy. Here, we summarize recent advances in the fabrication of smart bioinspired nanochannels and highlight their applications in energy conversion systems. Recent Advances in the Fabrication of Smart Bioinspired Nanochannels Materials and TechniquesThe fragility and instability of biological ion channels have motivated the development of smart bioinspired nanochan nels. To satisfy specific application requirements, various materials such as biological, [15] inorganic, [16] organic, [17] and composite materials [18] have been used to fabricate artificial nanochannels. Currently, nanochannels with diverse shapes and structures can be obtained using different techniques and Smart bioinspired nanochannels exhibiting ion-transport properties similar to biological ion channels have attracted extensive attention. Like ion channels in nature, smart bioinspired nanochannels can respond to various stimuli, which lays a solid foundation for mass transport and energy conversion. Fundamental research into smart bioinspired nanochannels not only furthers understanding of life processes in living bodies, but also inspires researchers to construct smart nanodevices to meet the increasing demand for the use of renewable resources. Here, a brief summary of recent research progress regarding the design and preparation of smart bioinspired nanochannels is presented. Moreover, representative applications ...
