Dextran is a promising drug carrier in biomedicine and is dubbed a "biological missile". As a macromolecule composed of multiple glucose units, the molecular weight of dextran can be tailored according to different applications, ranging from 1,000 to tens of millions. By conjugating with various substances, dextran can produce highly potent and low-toxic drugs. Compared to natural production and extraction, synthetic dextran has higher yields, lower costs, and greater stability, making it an inevitable choice for large-scale applications.

In the field of medicine, dextran has a wide range of applications. It is extensively utilized as a hemolytic diluent, anti-shock infusion, and other formulations, with massive consumption. Iron-containing dextran derivatives, especially iron dextran products, can prevent and treat anemia in humans and animals. Among them, 5% iron-containing derivatives are currently considered the best choice for iron deficiency anemia treatment, particularly suitable for iron supplementation in renal dialysis patients.

Dextran derivatives also have diverse functionalities. Firstly, they can serve as modeling agents, such as dextran sodium sulfate (DSS), the gold standard in colitis modeling research. Secondly, their excellent water solubility allows applications in drug delivery, tissue engineering, and more. Additionally, dextran derivatives can form stable glucosamine conjugates to prepare biosensors, drug delivery systems, etc. These properties make dextran derivatives highly promising research and application materials, providing ample opportunities to explore innovative drug delivery and therapeutic approaches.
