Summary: Protein molecules add rich functionality to nanoscale architectures, particularly in high-symmetry protein cages. This study introduces a method for designing protein assemblies, successfully creating cubically symmetric cages through a combination of two simpler symmetries. Experimental testing revealed the formation of the intended octahedral cage, while another design resulted in a collapsed structure of lower stoichiometry and symmetry, providing insights for improved creation of nanoscale protein architectures.

Summary: Soft matter with programmed macroscopic responses to molecular analytes, such as the nematic liquid crystal composition described in this study, shows potential utility in health and safety contexts. The composition undergoes a distinct phase transition in response to organoamine vapors, with the formation of long-lasting metastable nematic phases. By utilizing experimental and computational methods, it was concluded that a one-to-one heterodimer is the dominant species in this LC composition, offering a chemically selective way to report the presence of volatile amines.

Summary: The application of conjugated polymers in electronics, particularly in charge storage devices, biosensors, and microbial fuel cells, has been increasing. Recent studies have shown that immobilization of electroactive bacteria within conjugated polymers can enhance their electrical conductivity and charge storage. This review summarizes recent attempts to immobilize whole bacterial cells and their proteins on the surface or within conjugated polymers, such as poly(3,4-ethylenedioxythiophene) and polypyrrole, in order to design novel electrically-conducting biohybrid materials with potential applications in organic electronics and bioelectronics.

Summary: This study investigates the impact of aromatic clusters on protein stability by studying designed aromatic interactions within a protein cage. The results show that inter-subunit phenylalanine clusters enhance interhelix interactions and increase melting temperature. Theoretical calculations suggest that this is due to a transformation from T-shaped geometry to pi-pi stacking and hydration entropic gain at high temperatures. The isolated nanoenvironment within a protein cage allows for detailed analysis of multiple clustering residues, providing insights into biomolecular interactions and potential applications in bionanomaterial design.

Summary: In this study, a capillary-sensing platform based on liquid crystals confined in microcapillaries was developed for the detection of acetylcholinesterase (AChE) and its inhibitors. The LC droplets displayed distinct optical images in response to the presence or absence of AChE and AChE-inhibiting pesticides, enabling highly sensitive detection of pesticides. This LC-based microcapillary sensor shows great promise for simple, rapid, and label-free detection of pesticides in environmental samples.

Summary: Protein assemblies can be designed using protein crystals with highly ordered arrangements of protein molecules, which serve as useful matrices for synthesizing artificial protein assemblies. By engineering covalent and non-covalent interactions in a protein crystal, a supramolecular filament structure was constructed to achieve precise arrangement of protein molecules and prevent random aggregation caused by disulfide bonds. The successful synthesis of bundled filament from the crystals was accomplished by autoxidation of cysteinyl thiols after isolation from living cells.

Summary: Four-dimensional (4D) scanning transmission electron microscopy was used to study the electric fields at the edges of 2D semiconducting monolayer MoS2. Sub-nanometer 1D features in the 2D electric field maps were observed at the outermost region along zigzag edges and also along nanowire MoS-terminated MoS2 edges. The presence of low Z number atoms terminating many of the uniform edges was revealed through electric field reconstructions, along with integrated differential phase contrast reconstructions. Density functional theory calculations supported the formation of periodic 1D edge states and indicated the enhancement of electric field magnitude for some edge terminations. The experimentally observed electric fields at the edges were attributed to the absence of an opposing electric field from a nearest neighbor atom when the electron beam propagates through the 2D monolayer and interacts. These results highlight the potential of 4D-STEM in mapping the atomic scale structure and fluctuations of electric fields around edge atoms in 2D materials.

Summary: By confining alpha-sexithiophene (6T) molecules in boron nitride nanotubes (6T@BNNTs), fluorescence anisotropy can be induced in a transparent host. The experiments show that individual 6T@BNNTs exhibit high polarization extinction ratio at room temperature, and the fluorescence anisotropy is consistent with the alignment of encapsulated 6T molecules along the nanotube axis. By stretching a flexible transparent polymer film mixed with 6T@BNNTs, macroscopic fluorescence anisotropy can be induced within the film. This work demonstrates the use of dyes@BNNT system as a convenient platform to induce fluorescence anisotropy in photonic materials.

Summary: By conducting molecular dynamics simulations at different pH values, we studied how interfaces affect the stability of ferritins and the mechanism of ferritin disassembly. The simulations revealed that the dimer is the essential subunit for disassembly, and the slight swelling of the dimer resulting from monomer rotation triggers disassembly. The interface between dimers plays a crucial role in ferritin disassembly. The protonation of residues at low pH leads to the loss of salt bridges and hydrogen bonds between dimers, resulting in ferritin disassembly in an acidic environment.

Summary: In this study, a hierarchical protein assembly system with two distinct protein-protein interaction sites was constructed using an anisotropic-shaped protein needle. High-speed atomic force microscopy measurements showed the formation of unique tetrameric clusters through the N-terminal head of the protein on a mica surface. These clusters further self-assembled into a monolayer structure through the C-terminal His-tag. The results expand the toolbox for constructing hierarchical protein assemblies based on structural anisotropy.

Summary: The emergence of protein-based crystalline materials provides promising opportunities for enzyme immobilization. This study demonstrates the use of polyhedra crystals to simultaneously encapsulate the foreign enzymes FDH and the organic photocatalyst eosin Y. These hybrid protein crystals, prepared easily by cocrystallization within a cell, form solid particles at a scale of 1 μm without the need for complex purification processes. The immobilized FDH within protein crystals exhibits recyclability, thermal stability, and maintains 94.4% activity compared to the free enzyme. Additionally, the incorporation of eosin Y enables CO(2)-formate conversion activity in the solid catalyst through a cascade reaction. This work highlights the potential of engineering protein crystals for the development of robust and environmentally friendly solid catalysts for artificial photosynthesis.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
