dextrancoated

Dextrancoated refers to a surface or material that has been coated with dextran. Dextran is a complex branched glucan, a polysaccharide made up of many glucose molecules. It is synthesized by certain bacteria, most notably Leuconostoc mesenteroides, from sucrose. Dextrancoated surfaces are often employed in various applications due to the unique properties of dextran.

These properties include hydrophilicity, biocompatibility, and the ability to reduce non-specific protein adsorption. The hydrophilic nature of dextran means it readily interacts with water, creating a hydration layer on the coated surface. This hydration layer can act as a barrier, preventing other molecules, such as proteins, from attaching.

In biomedical fields, dextrancoated materials are used for implants, drug delivery systems, and biosensors. For instance, coatings on medical devices can help minimize immune responses and improve integration with biological tissues. In chromatography, dextran coatings are used to modify stationary phases, influencing separation characteristics. The application of dextran as a coating is typically achieved through methods like adsorption, covalent attachment, or plasma polymerization. The specific method chosen depends on the substrate material and the desired properties of the final dextrancoated surface.
