CM-dextran is widely used in biomedical and pharmaceutical applications due to its biocompatibility and water solubility. It serves as a carrier in drug delivery systems, enabling controlled release and improved stability of therapeutic agents. In tissue engineering, CM-dextran supports the formation of hydrogels that mimic extracellular matrices, facilitating cell growth and differentiation. It is also employed in chromatography for size-exclusion separation of biomolecules, particularly in purification processes of proteins and nucleic acids. Additionally, CM-dextran is used in ophthalmic solutions as a viscoelastic agent during surgical procedures, helping maintain space and protect delicate tissues. Its ability to modify surface properties makes it useful in coating medical devices to reduce protein adsorption and improve biocompatibility.
