Research progress of natural carbohydrate nano-drug delivery system

Nanotechnology, as one of the three emerging technologies that will affect human life in the future, its integration with the drug delivery system can not only maximize the pharmacological effects of the drug, but also overcome the limitations of the drug itself. Compared with traditional drug delivery methods. The effect of nano-drug delivery systems is more stable and less harmful. However, some drug carriers are lack of targeting, and problems such as low transfection efficiency and certain cytotoxicity also existed. Natural sugars have a wide range of sources, which are inexpensive, non-toxic, and have good biocompatibility and biodegradability as well. This article summarizes the system composition of nano-drug delivery systems. The point is focusing on using galactose, chitosan, dextran and pullulan and their derivatives as raw materials, which are targeted to their specific receptors after modified drug loading, and compared with those without carbohydrate modification. The drug carrier, and its ability to deliver drugs have been significantly improved. At the same time, the development trend of drug carrier in the future is prospected.
