Tailor-Made Polysaccharides for Biomedical Applications

ACS Applied Bio Materials, Год журнала: 2024, Номер 7(7), С. 4193 - 4230

Опубликована: Июль 3, 2024

Polysaccharides (PSAs) are carbohydrate-based macromolecules widely used in the biomedical field, either their pure form or blends/nanocomposites with other materials. The relationship between structure, properties, and functions has inspired scientists to design multifunctional PSAs for various applications by incorporating unique molecular structures targeted bulk properties. Multiple strategies, such as conjugation, grafting, cross-linking, functionalization, have been explored control mechanical electrical conductivity, hydrophilicity, degradability, rheological features, stimuli-responsiveness. For instance, custom-made known worldwide tissue engineering, drug/gene delivery, regenerative medicine. Furthermore, remarkable advancements supramolecular engineering chemistry paved way mission-oriented biomaterial synthesis fabrication of customized biomaterials. These materials can synergistically combine benefits biology tackle important questions. Herein, we categorize summarize based on methods, explore main strategies customize chemical structures. We then highlight properties using practical examples. Lastly, thoroughly describe tailor-made PSAs, along current existing challenges potential future directions.

Cross-Linked Organic Polymer with Amine/Dithiocarbamate Backbone: A Multipurpose Adsorbent for Removal of Dyes, Iodine, and Hg²⁺/Pb²⁺ from Wastewater

ACS Applied Polymer Materials, Год журнала: 2025, Номер unknown

Опубликована: Фев. 7, 2025

The contamination of freshwater by industrial pollutants poses significant health risks, highlighting the urgent need for cost-effective, multifunctional materials to remove diverse environmental pollutants. Motivated pressing need, we have developed a class tertiary amine-centered dithiocarbamate (DTC)-based cross-linked polymers (CPs) fast and efficient removal from environment. Furthermore, subsequent synthesis, tunability side chain was achieved integrating two different types functional groups: CP-1, which contains benzyl (aromatic) group, CP-2, incorporates methyl (aliphatic) group. synthesized were characterized via various techniques including solid-state 13C NMR, FT-IR, TG-DTA, SEM, EDAX, DSC. polymeric employed dyes, radioactive iodine, heavy metals toxic mercury lead ions. CPs removed iodine water as well air with an inordinate uptake capacity >6.5 g/g vapor phase, demonstrating very high uptake. In line, benzyl-containing CP has azo dyes within 5 s capacities, i.e., 2315.46, 1138.01, 588.23 mg/g Eriochrome Black T, Congo Red, Methyl Orange, respectively. Moreover, material effectively eliminated metals, (Hg2+) (Pb2+), capacities 316.56 98.70 mg/g, also been successfully in column chromatographic purification contaminated practical application. Overall, DTC-based are versatile materials, showed facile both aliphatic aromatic moieties, thermal stability able few seconds followed implementation.
