Summary: This study evaluates the effect of natural polysaccharide solutions (starch, alginate, and chitosan) on clay composite properties. The authors describe the process of obtaining gelated biopolymers and analyze characteristics such as viscosity and pH. Results show that increasing the concentration of biopolymer decreases the bulk density and shrinkage of clay composite materials. Additionally, the application of starch and alginate solutions enhances compressive strength and moisture adsorption degree, while also affecting the structure and water erosion behavior of the clay composite.

Summary: Starch, a copolymer with unique physicochemical characteristics, has limitations in food applications due to its undesirable properties. Different modification methods are used to improve its performance and expand its application. The addition of small amounts of polysaccharides affects the properties of starch pastes and gels, with factors such as starch type, polysaccharide type, and preparation methods playing a role. This review discusses the changes in starch properties and the mechanism of polysaccharide action on starch after modification.

Summary: Thermoplastic biofilms were produced from achira starch, chitosan, and nanoclays through solvent-casting, and the influence of sonication time on their properties was investigated. Longer sonication times resulted in stronger intermolecular interactions, improved mechanical properties, and more homogeneous materials. The films with 20 minutes of sonication exhibited satisfactory tensile strength and elongation, increases of 154% and 161% respectively. These materials showed lower hydrophilicity, making them potential candidates for coatings or packaging in the food industry.

Therefore, starch modification is carried out to enhance positive characteristics and eliminate limitations. This review summarizes possible starch modifications and their corresponding applications, both within and outside the plant system (physical, chemical, and enzymatic). Furthermore, it highlights the implications of adjusting different starch properties.

Summary: This study explored the interactions between gum arabic and alginate, finding that only specific fractions of gum arabic interact with alginate at pH 4. The intensity of interaction was significantly higher for glycoprotein compared to arabinogalactan protein. The findings suggest a potential electrostatic interaction between positively charged proteins in gum arabic and negatively charged carboxylate groups in alginate.

Summary: The detection of cancer biomarkers, especially using electrochemical biosensors based on conducting polymers (CPs) and their composites, has shown great promise in early diagnosis, treatment response determination, and disease progression monitoring. These CP-based biosensors possess high sensitivity and specificity due to the large surface area, porosity, and functional groups of CPs. They allow for the capture and detection of cancer biomarkers, such as DNAs, miRNAs, proteins, enzymes, neurotransmitters, and whole cancer cells, with significantly enhanced sensitivity and a limit of detection as low as 0.5 fM for miRNA and 10 cells for cancer cell detection. Multiplex biomarker detection and cell capture methods are considered the most promising category, offering more accurate and reliable results. This review provides a comprehensive summary of CP-based electrochemical biosensors and their potential applications in cancer diagnosis and treatment.

Summary: The genetic variants of HLAs play a crucial role in virus-host interaction and pathology of COVID-19, influencing both T and B cell immune responses. Certain HLA alleles, such as HLA-C*01 and HLA-B*44, increase susceptibility to COVID-19, while others like HLA-A*02:01, HLA-DR*03:01, and HLA-Cw*15:02 show resistance to SARS infection. Understanding the genetic association of HLA with COVID-19 is important for studying transmission and pathogenesis, and integrating HLA testing can help identify highly susceptible populations and aid in vaccine development.

Summary: Strict control over surface chemistry is required to study and regulate cell behavior at a biomaterial interface. Understanding cell adhesion in vitro and in vivo is increasingly important in tissue engineering and regenerative medicine. This work explores the use of organic layers prepared by electrografting of diazonium salts and their functionalization with biologically active molecules to promote cell adhesion. The experiments showed that modifying electrodes with diazonium salts and poly-L-lysine enhances cell adhesion, making it a valuable strategy for integrating bioelectronic devices with neural cells.

Summary: Recent studies have shown that electrochemical grafting of diazonium salts is an efficient method for forming heterogeneous catalysts. This review aims to evaluate the industrial applicability of diazonium-based catalysts, focusing on their mechanical, chemical, and thermal stability. Various approaches to catalyst production using diazonium salt chemistry have been compared, and the most common deactivation routes of catalysts have been discussed. However, more research is needed to experimentally verify the stability and long-term catalytic performance of diazonium-based catalysts.

Summary: In this study, three methods were proposed to improve the performance of chitosan-based films: using nanocellulose to reduce hydrophilicity, using bio-based plasticizer to enhance mechanical properties, and using chestnut extract as an antimicrobial agent. The properties of the films were evaluated immediately after preparation and after 7, 14, and 30 days, and it was found that the films maintained their stability over time. The addition of nanofillers did not affect the elongation at breaks or the thermal properties of the films, but it reduced transparency.

Summary: Alginate membranes with mixed magnetite and tetranuclear iron (III) molecular magnet fillers were studied to enhance ethanol dehydration via pervaporation. The synergistic effect of the fillers on transport parameters was discussed, showing that the addition of magnetite improved the magnetic properties of the molecular magnet while maintaining good dispersion. The alginate membrane with 2 wt% magnetite and 7 wt% molecular magnet exhibited the most effective water/ethanol separation process, with PSI and separation factor values of 8438.9 kg•m(-2)•h(-1) and 3425.5, respectively.

Summary: Due to the growing demand for antimicrobial packaging materials, biopolymers have been extensively investigated. In this study, the plasticization efficiency of bio-based plasticizers in sodium alginate compositions containing chestnut extract was examined, along with their effect on film properties. Different plasticizers were compared, and their interactions with the polymer matrix were analyzed. The obtained films exhibited hydrophilic and barrier properties, and those prepared with the proposed plasticizer showed better mechanical and antimicrobial properties.
