Obtaining chitosan hydrogels/Rosmarinus officinalis modified with plasma
Abstract
Hydrogels are three-dimensional networks with high water content, hydrogels have different properties according to the material with which they are obtained. This materials based on natural polymers have good biocompatibility and biodegradability properties, among others. However, these properties can be improved using plasma technology, which is a procedure with the ability to modify surfaces to functionalize, sterilize or polymerize a material. In the present work, hydrogels based on chitosan with different concentrations of glacial acetic acid were obtained, they were characterized by FTIR-ATR, DSC and TGA techniques. For the evaluation of biocompatibility, a hemolytic test was performed, and a blank was compared against a hydrogel with rosemary extract and another hydrogel with rosemary extract and modified with plasma. The results obtained showed that plasma technology is an innovative tool to improve biological properties by modifying surfaces.
