Abstract
Hydrogels network based on carboxymethylcellulose (CMC) and chitosan (CS), CC1 and CC2, have been prepared respectively in the presence or without the crosslinking agents [(N-hydroxysuccinimide (NHS)/N,N’-dicyclohexylcarbodiimide (DCC)] and characterized by FT-IR.
The swelling behavior in distilled water at 25°C and biological activities have been investigated. CC1 hydrogel revealed higher potential swelling than CC2. Hydrogels showed to possess an important antioxidant activity equal to 66.67% for CC1 and 57.27% for CC2, to scavenge hydroxyl radicals at 2mg/mL. And the values of their reducing power were approximately 53% and 57%.
From the hemolytic potential test the obtained materials were hemo-compatible. The anti-inflammatory activity exhibited that hydrogels were able to protect albumin from denaturation.
