Summary: In this study, we introduced the concept of isoelectric point (pI) barcode for species identification of raw meat by combining microcolumn isoelectric focusing (mIEF) and similarity analysis with the earth mover's distance (EMD) metric. We analyzed 14 meat species using mIEF to generate electropherograms of myoglobin/hemoglobin (Mb/Hb) markers, which were then converted into pI barcodes for EMD analysis. By developing a barcode database and using the EMD method, we successfully identified 9 meat products with the advantages of convenience, speed, and low cost.

Summary: This study investigated the possibility of using the zero-point charge (ZPC) as an alternative indicator for the aggregation of microplastics instead of the traditional zeta potential. The results showed that the IEP method could effectively achieve the removal of microplastics through aggregation with the optimized concentration of polyaluminum chloride (PAC) and within the appropriate pH range. However, the applicability of this method is limited by the initial pH, dosage of coagulant, and the type and size of microplastics.

Summary: This article reviews the mechanisms and kinetics of particle deposition at solid surfaces, focusing on the formation of self-assembled layers with controlled structure and density. The theoretical aspects, including linear transport under flow and diffusion, as well as the analysis of deposition kinetics in non-linear regimes affected by surface blocking, are briefly discussed. Experimental results for micro and nanoparticles are also discussed, along with the stability of layers and the release kinetics of silver particles. The applicability of quartz microbalance measurements for quantitative studies of nanoparticle deposition kinetics is examined. The review also analyzes representative results of virus deposition at abiotic surfaces and the formation of nanoparticle corona at polymer carrier particles. It argues that the results obtained for colloid particles can serve as reliable reference systems for the interpretation of protein and other bioparticle deposition, supporting the idea that simplicity is universal.

Summary: This study examines the effects of urea and ethanol additives on aqueous solutions of PSS and PDADMA. It is found that ethanol condenses at the hydrophobic backbone of PSS, increasing counterion condensation, while urea readily solvates both polyelectrolytes and replaces water in solvation. These differences influence the binding configurations in PSS-PDADMA complexation, with ethanol loosening the complex and urea pushing the polyelectrolyte chains further apart. Overall, these findings have significance in tuning the mechanical and swelling characteristics of polyelectrolyte materials through solution additives.

Summary: This study investigated the deposition kinetics of positively charged prolate spheroid-shaped polymer microparticles on silica and gold sensors using the quartz microbalance (QCM) technique. The frequency and bandwidth shifts of various overtones were measured as a function of time. The results showed a close to unity ratio for all overtones, which was interpreted in terms of the hydrodynamic model. The results obtained from the QCM method were compared with theoretical modeling and showed good quantitative agreement, especially when considering particle slip relative to the ambient oscillating flow. The study highlights the importance of considering hydrodynamic slip effects when interpreting QCM kinetic results for bioparticles, particularly viruses.

Summary: Streaming potential and quartz crystal microbalance measurements were used to investigate the pH dependency of the adsorption of poly-L-lysine (PLL) and poly-L-arginine (PARG) on alpha-quartz surface, which was further supported by all-atom molecular dynamics simulations. The adsorption behavior was determined by the change in the number of peptide-surface ion pairs and the repulsive electrostatic interactions between the polypeptides. Low pH favored strong adsorption and stable monolayers, while high pH resulted in weakly bound but denser peptide films with limited stability. Electrostatic interactions, hydrogen bonding, and non-specific interactions played important roles in the adsorption process.

Summary: We demonstrate that pH significantly affects the assembly mechanism and properties of PLL and PGA complexes through a combination of experimental characterization and molecular simulations. Various techniques, including DLS, LDV, ITC, CD, and AUC, are employed to assess the complexation, charge state, thermodynamics, secondary structure, and molecular weights of the peptides. Molecular dynamics simulations provide insights into the binding changes and hydrogen bonding involved in the complex formation. Our findings reveal the pH dependency of PLL/PGA complexation and highlight the potential of pH control in designing peptide materials.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.
