Chitosan-based Biomaterials Characterization

Example 10

FIG. 25 shows the ultimate suture pullout load for acetyl-chitosan, butyryl-chitosan, chitosan powder and Na₂CO₃ chitosan when wet or dry.

FIG. 26 shows the weight gain or swelling after exposure to a hydrophilic solvent of chitosan power, acetyl-chitosan, butyryl-chitosan, regenerated (deacylated) chitosan and Na₂CO₃ treated chitosan. The butyryl-chitosan and the regenerated electrospun chitosan nanofibers show good cytocompatibility, structural stability, suggesting future exploration in tissue engineering applications.

FIG. 27 shows x-ray diffraction of chitosan power, Na₂CO₃ treated chitosan fibers, as-spun chitosan and acetyl-chitosan.
