“…SPVs with bilayer membrane structures are good candidates for CSs because of the enrichment effect of the functional moieties on their surfaces . On the basis of our previous knowledge of SPVs as smart drug delivery system and a CO 2 ‐responsive artificial polymer nanochannel as gas sensors, we constructed supramolecular hyperbranched polymer (SHP) vesicles containing porphyrin (PP) and β‐cyclodextrin (β‐CD)/azobenzene (Azo) host–guest interactions as a fluorescent CS for Zn 2+ sensing with a high selectivity, high sensitivity, and wide range of detection limit. Our strategy was first to obtain an SHP precursor containing β‐CD/Azo host–guest binding sites through macromonomer polymerization (Scheme A, B).…”

Chemosensors (CSs) with dynamically tunable detection ranges have important significance for their expansion in practical applications; however, most CSs possess an unchangeable detection limit. In this work, we report the first example of a supramolecular polymer vesicle (SPV) chemosensor with a dynamically tunable detection range. SPVs containing porphyrin (PP) moieties and β-cyclodextrin (β-CD)/azobenzene (Azo) host-guest interactions were first constructed. The obtained SPVs were used to detect Zn with a high selectivity and sensitivity over a wide detection limit range of 8.67×10 to 1.99×10 under UV light irradiation. The corresponding sensing mechanism was attributed to the synergistic effects of the triple noncovalent interactions, including the metal-ligand coordination of PP/Zn and the double host-guest interactions of β-CD/Azo and β-CD/PP.

“…Another CO 2 ‐induced gating mechanism inspired by olfactory sensory neurons (OSN) of mosquitoes was presented more recently . In that work, conical polyimide single nanochannels were chemically modified by anchoring (NHSS/EDC chemistry) (1‐(4‐amino‐phenyl)‐2,2,2‐tri‐fluoro‐ethanone) (APTE) ( Figure a–c).…”

Solid‐state nanopores are fascinating objects that enable the development of specific and efficient chemical and biological sensors, as well as the investigation of the physicochemical principles ruling the behavior of biological channels. The great variety of biological nanopores that nature provides regulates not only the most critical processes in the human body, including neuronal communication and sensory perception, but also the most important bioenergetic process on earth: photosynthesis. This makes them an exhaustless source of inspiration toward the development of more efficient, selective, and sophisticated nanopore‐based nanofluidic devices. The key point responsible for the vibrant and exciting advance of solid nanopore research in the last decade has been the simultaneous combination of advanced fabrication nanotechnologies to tailor the size, geometry, and application of novel and creative approaches to confer the nanopore surface specific functionalities and responsiveness. Here, the state of the art is described in the following critical areas: i) theory, ii) nanofabrication techniques, iii) (bio)chemical functionalization, iv) construction of nanofluidic actuators, v) nanopore (bio)sensors, and vi) commercial aspects. The plethora of potential applications once envisioned for solid‐state nanochannels is progressively and quickly materializing into new technologies that hold promise to revolutionize the everyday life.

“…The ultrahigh gating ratio reached 1250, showing excellent gating perfor mance. [54] Furthermore, our group applied cellular principles to the construction of artificial CO regulated ion nanochannels inspired by smooth muscle vasodilation (Figure 4c iv). [55] The mechanism relies on the fact that CO has a higher affinity for ferroporphyrin compared with carboxyl groups on the surface of the nanochannels.…”

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 ...
