Abstract
- To improve the hemostatic function of chitosan nanofiber mats, we studied the synergetic effects of gelatin blending and porosity control. Gelatin-blended-chitosan (Chi-Gel) nanofiber mats were evaluated with respect to surface morphology, mechanical properties and wettability, and functionally tested in a blood clotting study. The blood clotting efficiency of Chi-Gel nanofiber mats using rabbit whole blood in vitro was superior to that of chitosan nanofibers. Moreover, Chi-Gel nanofiber mats with enlarged porosity, produced by ultra-sonication, showed improved blood clotting efficiency, cell viability and cell infiltration compared with non-sonicated Chi-Gel nanofiber mats. Field-emission scanning electron microscopy revealed a richer density of platelets on sonicated nanofiber mats than on non-sonicated nanofiber mats after 3 min of blood clotting. The proliferation of human dermal fibroblast cells on sonicated Chi-Gel nanofiber mats using the DNA assay was higher than that on non-sonicated chitosan nanofiber mats after 7 days of culture. Confocal z-stack images showed that sonicated Chi-Gel nanofiber mats with high porosity supported active cell migration and infiltration into the 3-dimensional nanofiber mats. These results suggest that hydrophilic gelatin blending and sonication of chitosan nanofiber mats yields synergistic effects that not only improve hemostatic function but also promote wound repair.
