Summary: Proteins can form robust bioadhesive materials through an α-helix-mediated interfacial adhesion model. Reduction of disulfide bonds in proteins leads to the gathering of α-helices at the solid/liquid interface, exposing hydrophobic residues and disrupting the hydration layer. This model provides a unique strategy for preparing protein nanofilms with well-defined layering, exhibiting strong adhesion and resistance to various conditions.

Summary: Flavonoids are secondary metabolites commonly found in plants, known for their antioxidant properties, involvement in plant defense mechanisms, and responsibility for the pigmentation of fruits and flower petals. Consumption of foods rich in flavonoids brings various health benefits such as blood pressure regulation, anti-aging effects, and anti-cancer properties. Infrared and Raman spectroscopy are effective methods for quickly and accurately determining the presence of flavonoid compounds in test samples. These methods have been successfully applied in the food and pharmaceutical industries. The spectroscopic spectra of different flavonoid subgroups (flavones, isoflavones, flavanones, flavonols, and anthocyanins) are compared and described in this review.

Summary: FT-IR and FT-Raman spectroscopies were used to investigate the interaction between polyphenols and gluten proteins in gluten dough. It was found that different polyphenols induced different changes in the secondary structure of gluten proteins, which were closely related to the number and type of functional groups, as well as the molecular size of the polyphenols.

Summary: The life cycle of SARS-CoV-2 is influenced by the environmental redox state, with a reducing environment impairing spike protein binding to ACE2 and an oxidizing environment promoting their interaction. Synthetic low molecular weight thiols induce a more reduced state in the receptor binding domain of the spike protein, impairing ACE2 binding and interfering with protein folding and viral replication. These thiols could potentially serve as innovative anti-SARS-CoV-2 therapeutics.

Summary: This study utilized FT-Raman and THz-TDS spectroscopy techniques to measure the TRS, showing a good correlation between disulfide concentration and characteristic peak intensities, with correlation coefficients of 92.2% and 95.4% for FT-Raman and THz-TDS data, respectively. Solid-state density functional theory analysis revealed that both Raman and terahertz vibrational spectroscopy techniques can quantitatively analyze the ratio of cysteine/cystine, providing a new method for biological analysis of sulfur-containing amino acids and related mixtures in basic science.

Summary: This paper presents a comparative numerical study of three notch-type compliant joints (groove, elliptical holes, and rectangular holes) in terms of their folding/unfolding performance. The results show that the geometric parameters of the joints are correlated with performance indicators, and the transition behaviors of folding/unfolding stiffness are associated with a certain range of rotational angles. Considering various performance aspects, the groove joint is recognized as the most suitable for folding a planar plate.

Summary: Photoperiod responsiveness is crucial for soybean production and adaptability. In this study, two qualitative genes controlling the long-juvenile trait in soybean were identified on scaffold_32 and chromosome 18. The LJ32 gene was identified as Tof11, a pseudo-response-regulator gene, while LJ18 was identified as a novel PROTEIN FLOWERING LOCUS T-RELATED gene, Glyma.18G298800. The natural variants of these genes play a role in regulating the long-juvenile trait in tropical regions.

Summary: The addition of polyphenols to wheat dough modifies the structure and mechanical properties of the gluten network. Different concentrations of phenolic acids induce changes in the secondary structure of gluten proteins, with hydroxybenzoic acids causing more structural changes. Moreover, dough treatment with hydroxycinnamic derivatives results in faster dough breakdown compared to hydroxybenzoic acids, indicating stronger interactions with the gluten network.

Summary: Through the use of Gaussian network model and molecular dynamics simulations, it has been confirmed that the folding process of protein 2GB1 is a two-state process with a major free-energy barrier, with the folding nucleus located in the beta-sheet domain. The destruction of the beta-sheet domain causes the transition from native to non-native structure, and constrained MD simulations show that the structural topology retained by the folding nucleus remains unchanged.

Summary: Food-mediated transmission of viral pathogens is a concern in food safety and public health. Raman spectroscopy provides valuable information for detecting viruses, with advancements in sensitivity and techniques like confocal Raman, surface-enhanced Raman scattering, and coherent anti-Stokes Raman scattering. The method allows rapid and minimal sample preparation for point-of-care testing, but challenges remain in its further development for food safety testing.

Summary: This report introduces a method for preparing polyacrylamide materials with unique surface morphology. By cross-linking and reduction reactions, the smooth polymer surface is transformed into submicron cubic clusters impregnated with silver nanoparticles. The resulting material resembles the Great Barrier Reefs in overall morphology and features a high content of active silver nanostructures. It demonstrates versatility in surface-enhanced Raman scattering and methanolysis catalysis. These methods enlarge the surface area of the shape-adapting polymer material while generating minimal chemical waste.

Summary: We report the fabrication of a SERS sensor using alumina beads as the solid support and demonstrate its high sensitivity with the model analyte 4-APDS. The key to sensitivity is a hydrophilic-hydrophobic surface gradient constructed by sequentially coating with surfactant and fluorous silane. The practicality of the sensor beads is evidenced by successfully tracking the SERS fingerprints of five food colorant standards.
