Summary: Self-assembling peptides with proline as a beta-breaker and diphenylalanine motif were studied for their ability to form diverse nanostructures. The stereo-configuration of amino acids played a crucial role in directing these peptides to assemble into nanoparticles, nanotapes, or fibrils. Additionally, the study found that heterochirality could strategically interfere with pathological processes, potentially offering future therapeutic applications with resistance to degradation and biocompatibility.

Summary: This study reports the self-assembly of peptides into hierarchical helical arrays capable of emitting circularly polarized luminescence (CPL), with the handedness of the CPL signals controlled by changing the amino acid sequence. The peptide HHAs provide hydrophobic pockets for accommodating fluorescent molecules with helical arrangement, leading to the generation of CPL signals with high g(lum) values. This work paves the way for constructing highly ordered chiral materials with potential applications in the chiroptical field.

Summary: Extensive 2-D platinum nanowire network (NWN) sheets are created through a hierarchical self-assembly process with the aid of biomolecular ligands. The Pt NWN sheet is assembled from the attachment growth of 1.9 nm-sized nanocrystals into nanowires featuring a high density of grain boundaries, which then interconnect to form monolayer network structures extending into centimeter-scale size. The Pt NWN sheets exhibit outstanding oxygen reduction reaction (ORR) activities, with specific and mass activities 12.0 times and 21.2 times greater than those of current state-of-the-art commercial Pt/C electrocatalysts.

Summary: The study found that tree-shaped fractal patterns could be self-assembled from Fmoc-Glu and ZnTPyP, composed of nanorod aggregate arranged in a spiral fractal way. The formation and growth of initial nucleon led to the fractal patterns, and the spiral packing and their branches were closely related to the absolute configuration of Fmoc-Glu.

Summary: This study presents a novel strategy of achieving higher hierarchical structures through cooperative self-assembly of hydrophobic tripeptides with reverse sequences, showing a low-to-high hierarchical structure transformation. The cooperation between different sequences also allows different morphological transitions, promoting a more compact molecular arrangement by creating more hydrogen bond interactions and in-register π-π stacking in the anti-parallel β-sheet conformation. This work provides a handy approach for controlled hierarchical assembly and the development of various functional bionanomaterials.

Summary: This study reports on the formation and characterization of self-assembled membranes made with & lambda;-carrageenan and cationic & beta;-sheet peptides. The results show that the polysaccharide conformation, solution viscosity, and interactions between polysaccharides and peptides affect the properties of the membranes. The interplay between polymer-peptide interactions and polysaccharide chain stiffness could be used to control the structure-function relationship of the membranes.

Summary: Porous materials with nanometer-scale pores have important applications as nanoporous membranes. In this study, ABA triblock copolymers were used as precursors to produce nanoporous polymeric membranes (NPMs) in thin film form by degrading the end blocks. Polycyclooctene (PCOE) NPMs with tunable pore sizes were successfully prepared using solvent casting technique. Oxygen plasma etching was employed to improve the surface porosity and hydrophilicity of the membranes. This study provides a straightforward method to produce tough NPMs with high porosity and hydrophilic surface properties.
