Dextran T70 (MW 70,000) is a complex carbohydrate polymer composed of glucose molecules linked by glycosidic bonds. It is highly soluble in water, making it suitable for use as a viscosity regulator or stabilizer in foods, paints, and adhesives. In the biomedical sector, dextran is frequently utilized as a plasma expander due to its capability to increase blood volume when administered intravenously. Additionally, it can be modified to create dextran-based drug delivery systems, such as targeted nanoparticles.
