Dextran is widely used in the medical field as a plasma volume expander to treat or prevent shock caused by severe blood loss, burns, surgery, or trauma. It helps maintain blood pressure and circulation by increasing the volume of blood plasma. Additionally, dextran is employed in medical diagnostics, such as MRI, as a component of contrast agents to enhance imaging clarity of internal organs. It is also used in the production of certain pharmaceuticals, where it acts as an excipient to stabilize, enhance delivery, and control the release of active ingredients. In laboratory settings, dextran is utilized in chromatography and density gradient centrifugation for separating and purifying biomolecules like proteins and cells due to its ability to form gels with specific pore sizes and density differences. It is further used in the manufacturing of biodegradable hydrogels for wound healing and drug delivery systems. Furthermore, dextran finds application in the food industry as a thickener, stabilizer, and texturizer in various products. Its biocompatibility and versatility make it a valuable material in both medical and industrial applications.
