“…Vesicular photocatalytic systems have also been extensively developed till date by using molecular PSs and catalysts with hydrophobic alkyl functional groups. − This approach enables the utilization of water-insoluble PSs and catalysts in the aqueous phase by immobilizing them onto the lipid bilayer vesicle surface. Although photocatalytic H 2 production by the combination of photosensitizing QDs and molecular catalysts on the lipid vesicle surface has been reported, the combination of DSP and lipid vesicles has been scarcely reported to date. , Therefore, in this study, we synthesized a Ru(II) molecular PS with four hydrophobic nonyl chains and two hydrophilic methylphosphonate anchors, [Ru(dC 9 bpy) 2 (H 4 dmpbpy)] 2+ (Figure b; RuC 9 = [Ru(dC 9 bpy) 2 (H 4 dmpbpy)] 2+ ; dC 9 bpy = 4,4′-dinonyl-2,2′-bipyridine, H 4 dmpbpy = 4,4′-dimethyl phosphonic acid-2,2′-bipyridine) and prepared a H 2 production system of DSP nanoparticle, RuC 9 @Pt-TiO 2 , by immobilizing RuC 9 on the surface of Pt-cocatalyst-loaded TiO 2 nanoparticles.…”

Dye-sensitized H2 evolution photocatalysts have attracted considerable attention as promising systems for the photochemical generation of H2 from water. In this study, to mimic the reaction field of natural photosynthesis artificially, we synthesized a hydrophobic Ru(II) dye-sensitized Pt-TiO2 nanoparticle photocatalyst, RuC 9 @Pt-TiO2 (RuC 9 = [Ru(dC9bpy)2(H4dmpbpy)]2+; dC9bpy = 4,4′-dinonyl-2,2′-bipyridine, H4dmpbpy = 4,4′-dimethyl phosphonic acid-2,2′-bipyridine), and integrated it into 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) lipid bilayer vesicle membranes. The photocatalytic H2 production activity in 0.5 M l-ascorbic acid aqueous solution enhanced by more than three times in the presence of DPPC vesicles (apparent quantum yield = 2.11%), whereas such a significant enhancement was hardly observed when the vesicle formation was omitted. These results indicate that the highly dispersed state of the hydrophobic RuC 9 @Pt-TiO2 nanoparticles in the DPPC bilayer vesicles is a key factor in achieving enhanced photocatalytic H2 production activity in aqueous solution.

“…[ 13 ] These studies have not only deepened our understanding of biological ion channel proteins but also provided inspiration for the development of novel artificial nanochannel‐structured membranes for transporting specific ions. For example, reconstituted ion channels can be directly obtained after inserting extracted biological ion channel proteins [ 14–21 ] or artificial components with channels [ 22,23 ] in phospholipid bilayers. Reconstructed EcClC proteins embedded in lipid bilayers can function as H + and Cl − pumps with improved and controllable transport properties because of the superimposing or counterimposing gradients of H + and Cl − ions.…”

Unique membrane structures endow membranes with controlled ion transport properties in both biological and artificial systems, and they have shown broad application prospects from industrial production to biological interfaces. Herein, current advances in nanochannel‐structured membranes for manipulating ion transport are reviewed from the perspective of membrane structures. First, the controllability of ion transport through ion selectivity, ion gating, ion rectification, and ion storage is introduced. Second, nanochannel‐structured membranes are highlighted according to the nanochannel dimensions, including single‐dimensional nanochannels (i.e., 1D, 2D, and 3D) functioning by the controllable geometrical parameters of 1D nanochannels, the adjustable interlayer spacing of 2D nanochannels, and the interconnected ion diffusion pathways of 3D nanochannels, and mixed‐dimensional nanochannels (i.e., 1D/1D, 1D/2D, 1D/3D, 2D/2D, 2D/3D, and 3D/3D) tuned through asymmetric factors (e.g., components, geometric parameters, and interface properties). Then, ultrathin membranes with short ion transport distances and sandwich‐like membranes with more delicate nanochannels and combination structures are reviewed, and stimulus‐responsive nanochannels are discussed. Construction methods for nanochannel‐structured membranes are briefly introduced, and a variety of applications of these membranes are summarized. Finally, future perspectives to developing nanochannel‐structured membranes with unique structures (e.g., combinations of external macro/micro/nanostructures and the internal nanochannel arrangement) for mediating ion transport are presented.

The utilization of metal organic framework (MOF) nanocomposites in various biomedical applications has been widely studied because of their unique properties. In recently years, Prussian blue (PB) is widely used in clinical studied due to its biosafety, which has already been approved by USA Food and Drug Administration (FDA). Therefore, it is great urgent to systematically summarize the resent progress to better serve the broad community of researchers. This review focuses on the properties of PB and PB analogues (PBA), and their applications in biological field. A systemic introduction of the properties is presented, including abilities of photothermal, scavenging of reactive oxygen species and adsorption. A variety of biomedical applications, such as tumor therapy, anti‐bacterial infection, biosensor, bioimaging, excretion, ischemic stroke treatment, etc. have been discussed as well. Furthermore, the challenges, key factors, and the prospects in the clinical transformation of PB or PBA are simultaneously discussed. This review will provide reference and guidance for the design and application of PB and PBA in the future.
