Research on Biological Performance of Partially Oxidized Calcium Alginate Gel

Article Preview

Abstract:

The degradable and well-distributed calcium alginates were obtained successfully by ionically cross-linking reaction which was the oxidized Sodium Alginate reflected with calcium ions. Their biological performances were investigated by testing swelling ratio, compression strength and degradation. The effects of oxidation degree and cross-linking density on the properties of calcium alginate were assessed. The results show the swelling ratios of samples were almost no effect whether modified or unmodified, furthermore modified calcium alginate had better degradation performance than unmodified.Lastly, oxidation may reduced the compression strength of samples,but increasing of ionically cross-linking density can enhance the mechanical strength.
