چکیده مقاله
Nowadays, the nanofiber hydrogel composites has attracted a lot of attention in tissue engineering due to having morphological similarity with the soft tissues In present study, we fabricated gelatin nanofibers through the wet spinning method to be used as a reinforcing agent within hydrogel in our future study The used concenrration, flow rate and voltage to fabricate gelatin nanofibers were 19% w/v, 0 5 to 0 7 ml/h and 15 to 17 kV respectively Then the nanofibers were chopped using a probe sonicator with a power of 80 Watts, and crosslinked using EDC/NHS The SEM images of fabricated nanofibers showd that they have average diameter of 455±58 nm and average length of 10 18±2 3 μm The chemical structure of the nanofibers was analyzed by FTIR The cross linking degree of the fibers was also investigated using the ninhydrin method that demonstrate that about 63 8 of amine groups of gelatin nanofibers are consumed in crosslinking reaction
