| Abstract: | Sodium alginate hydrogel has been widely used as biomedical materials in drug delivery system, tissue engineering scaffolds, antibacterial material and wound dressing, due to their superior biocompatibility and resemblance to biological tissues. Based on the brief introduction of physicochemical properties of sodium alginate, the progress of preparation methods of sodium alginate hydrogel cross-linked by non-covalent bonds is summarized including electrostatic interaction, hydrogen bonds, van der Waals forces and hydrophobic effects, etc. Meantime, the characterization methods on properties of sodium alginate hydrogel are also concerned. Finally, some problems related to the development of preparation and characterization methods are discussed. |
