Collagen/cellulose nanofiber hydrogel scaffold: physical, mechanical and cell biocompatibility properties

Collagen hydrogel applications in tissue engineering are limited due to its weak physical and mechanical properties, e.g. loss of water, destruction in the biological medium, weak mechanical properties, and handling difficulty. To improve the physical and mechanical properties of collagen hydrogel, cellulose nanofibers (CNF) were introduced to the collagen hydrogel. Up to 8% CNF, by total dry weight, was added to cold collagen acidic solution...
