Dextran is a polysaccharide composed of D-glucose monomers linked by glycosidic bonds. The structure is rich in hydroxyl groups, making it easy to chemically modify. The active groups on glucan can simultaneously load multifunctional molecules (enzymes, antibodies, peptides, nucleic acids, etc.), facilitating the preparation of multifunctional microspheres. It has now been widely used in two-dimensional and porous soft tissue scaffolds, drug release and other fields. Additionally, dextran gel is a polymer compound with three-dimensional mesh structure. https://www.cd-bioparticle...
