Resumen

En el presente trabajo se evaluaron materiales poliméricos a partir del aceite de higuerilla, por medio de transesterificación se obtuvieron tres variaciones de polioles (183, 196 y 236 mg KOH/g). Los cuales reaccionaron con diisocianato de isoforona para conformar una matriz de poliuretano, adicionalmente se incorporó quitosano en diferentes concentraciones (0, 2.5, 5 y 7.5 %p/p) con el fin de mejorar la viabilidad celular del polímero. El objetivo del estudio se centró en determinar el efecto de la adición de quitosano a la matriz de poliuretano sobre la viabilidad celular y así establecer si la mezcla tiene potencial para ser usada en aplicaciones biomédicas. Se evaluó la viabilidad celular in vitro de los polímeros y de sus extractos por medio del ensayo MTT sobre fibroblastos embrionarios de ratón L-929 (ATCC® CCL-1). Adicionalmente, se estudió una degradación acelerada de éstos en buffer fosfato a una temperatura de 105ºC por 72 horas. Se encontró que el incremento en la funcionalidad del poliol favorece la viabilidad celular y la adición de quitosano no afecta la proliferación celular. Además, se evidenció la resistencia a la degradación con valores menores a 1%. Con base en los resultados obtenidos, se concluyó que los polímeros pueden tener un alto potencial en aplicaciones biomédicas.
