제목 Advanced Catechol-modified Chitosan hydrogels with the Inducement of Iron (III) and Periodate Ion at Acidic condition
초록 Chitosan (CS) is a naturual polycationic polysaccharide and pH sensitive polymer with incomplete deacetylation form claiming chitin. It also a guaranteeing material in terms of pharmaceutical, chemical, and sustenance industry due to its exceptional structure. In this study, a catechol-functionalized chitosan (CCS) for an eminent level for substitution was synthesized and propelled by marine mussel cuticles in place on research those intricate connections between Fe3+ and catechol under acidic conditions. The ratios of catechol, chitosan and other reagents decide the structure of the hydrogel. The gel formation is then well-maintained by dual cross-linking through electrostatic interactions between CCS and oxidative ions through covalent catechol-coupling-based coordinate bonds. The hydrogels showed enhanced cohesiveness at lower pH due to coordinate bonds inspired by mussel byssal threads.
