Dextran-based polymer matrix

Dextran-based polymer matrices are hydrophilic biomaterials engineered from dextran—a nontoxic, biocompatible, branched polysaccharide produced by bacteria and composed mainly of α-1,6-linked glucose residues. Chemical modifications allow dextran to form hydrogels, scaffolds, and micelles with tunable mechanical properties, degradation rates, and drug release profiles. These materials are widely used in drug delivery, tissue engineering, and regenerative medicine due to their ability to encapsulate bioactive compounds, promote neovascularization and skin regeneration, and serve as substrates for cell growth and detachment. While dextran-based matrices are not molecular targets, their design significantly impacts therapeutic efficacy and safety in numerous biomedical fields. Rare safety concerns include hypersensitivity, overload syndromes, and kidney injury in some clinical settings.
