摘要

The intrinsic biodegradable characteristics, muco-adhesion, antimicrobial capabilities, and tunable acidic and basic response of polysaccharide-based biomaterials have made them a multifaceted diverse class of naturally derived polymeric materials with substantial prospective possibilities in biological sciences, pharmaceutical research, and medical research. The modifications or customization of their physicochemical along with functional characteristics to suit particular biomedical applications has been made possible by contemporary developments in blending, cross-linking, along with chemical modifications. With an emphasis on their utilization in the areas of tissue engineering, drug delivery, and wound healing, this review meticulously evaluates the biological, mechanical, morphological microstructural, and structural characteristics of polysaccharide-derived materials, including grafting copolymers, hydrogels, and composites as well.
