Obtención de hidrogeles de quitosano/Rosmarinus officinalis modificados con plasma
Resumen
Los hidrogeles son redes tridimensionales con gran contenido de agua, tienen diferentes propiedades de acuerdo al material con el que se obtengan. Estos materiales a base de polímeros naturales presentan propiedades de biocompatibilidad, biodegradabilidad, entre otras. Sin embargo, estas propiedades pueden mejorarse utilizando tecnología de plasma, el cual es un procedimiento con la capacidad de modificar superficies para funcionalizar, esterilizar o polimerizar un material. En el presente trabajo se obtuvieron hidrogeles a base de quitosano con diferentes concentraciones de ácido acético glacial, se caracterizaron por las técnicas FTIR-ATR, DSC y TGA. Para la evaluación de la biocompatibilidad, se realizó un ensayo hemolítico, y se comparó un blanco, contra un hidrogel con extracto de romero y otro hidrogel con extracto de romero y modificado con plasma. Los resultados obtenidos demostraron que la tecnología de plasma es una herramienta innovadora para mejorar propiedades biológicas al modificar superficies.
