Summary: Cholesterol-enhanced pore formation is an evolutionary mechanism utilized by cholesterol-free bacterial cells to specifically target cholesterol-rich eukaryotic cells. Researchers have developed a class of artificial cholesterol-dependent nanopores that can be modulated by cholesterol levels to control pore formation and channel activity. The most active channel has a nano-sized cavity, allowing transportation of nanometer-sized molecules and displaying potent anticancer activity against human hepatocellular carcinomas.

Summary: Nanopores in thin membranes have significant roles in science and industry. Single nanopores have been crucial in portable DNA sequencing and understanding nanoscale transport, while multipore membranes facilitate food processing and water and medicine purification. Although both fields utilize nanopores, they differ in terms of materials, fabrication, analysis, and applications. This Viewpoint proposes synergistic crosstalk between the two fields to enhance fundamental understanding and the development of advanced membranes. By improving communication and harmonizing measurements and modeling, the rational design of porous membranes can be enhanced.

Summary: Synthetic nanopores have been developed for applications in membrane filtration technologies and biomolecular sensing, but challenges remain in providing them with atomically defined shape and deliberate placement of chemical groups. A chemically defined transmembrane nanopore, EPM, demonstrates stable transmembrane transport functionality, particularly with up to 21-fold selectivity for potassium over sodium ions.

Summary: Water confined within hydrophobic spaces can undergo cooperative dewetting transitions driven by the number of waters within the pore as the collective variable. The dewetting free energy of nanoscale pores is determined by the effective surface tension coefficients of water-air and water-pore interfaces, while amphipathic cosolvents like alcohols can significantly shift the wet-dry equilibrium in biological systems.

Summary: Inspired by natural photosynthesis, light has become an emerging regulator and source of ion behavior in nanofluidics. Nanoprocessing technology has allowed the connection between light-regulated nanofluids and the optoelectronic properties of 2D materials, leading to applications in energy harvesting and enhancing our understanding of nanofluidics.

Summary: This study constructs a nanoconfinement by blocking a single nanopore with a nanoparticle, leading to anomalous and ultra-mechanosensitive ionic transport. The pressure-induced rotation of nanoparticles and resulting physical structure changes in the blocked nanopore are correlated with ion conduction and rectification, providing new opportunities for bio-inspired nanofluidic applications.

Summary: This study focuses on the electrokinetic energy conversion, electroviscous effect, and induced internal and external magnetic fields in a smart polyelectrolyte grafted soft nanopore with pH responsiveness. The researchers used an efficient molecular theory approach to analyze the total free energy of the system, considering the conformational entropy, electrostatic interactions, and chemical equilibrium reactions. The model predictions were found to be in agreement with analytical solutions, and the effects of various environmental and polymer brush parameters were discussed. The study concludes that the electrokinetic energy conversion efficiency is optimal at moderate pH values and low salt concentrations, and it is influenced by both the environmental and polymer brush properties. The study also highlights the potential of using magnetic field readouts for measuring streaming currents and controlling internal and external magnetic fields.

Summary: In this study, asymmetric double-layer graphene stacks with charged nanopores were constructed and the ion current rectification phenomenon was observed. The trapping behavior of cations and anions in the nanochannels was found to be optimal at a specific electric field. The underlying mechanism of the rectification effect was elucidated based on the dependence between ion current and carrier concentration.

Summary: A new injectable strategy using black phosphorus nanosheets for wireless neural stimulation without cell modifications has been described, showing high biocompatibility and degradation properties. The nanosheets act as miniature near-infrared light transducers to locally heat neural cells, reliably triggering neural activity both in vitro and in vivo. This approach also demonstrated successful high-frequency stimulation and potential for clinical applications, providing a promising alternative for neural stimulation.
