Hydrogels have been broadly used for a variety of biomedical applications including wound-healing bioadhesives, artificial kidney membranes, articular cartilage, organ reconstruction material, and artificial skin. Natural polymer hydrogel were prepared and their properties were determined in order to select the most appropriate setting method, drug delivery material. The hydrogels were made from gellan gum, xanthan gum, curdlan, chitosan and cross-link agent. Hydrogels obtained were characterized in terms of gel content, viscosity, swelling ratio, sol-gel transition temperature, mechanical and thermal properties maximum stress(MS), tensile strength(TS), elongation(E), differential scanning calorimetry analysis(DSC). The resultant hydrogels were flexible and elastic in the dry state. Hydrogel added cross-link agent showed higher gel content, viscosity and tensile strength than hyrdogel without cross-link agent. The in vitro degradation tests showed delayed swellings properties of the hydrogels.
