<p>The present invention provides a biomedical material comprising a shark-derived collagen; a biomedical material comprising a shark-derived collagen and hydroxyapatite; and methods for preparing the same. Since the biomedical materials of the invention comprise a shark-derived collagen which is low in antigenicity and high in biocompatibility, they do not cause rejection and they produce effects of good adhesion to organisms and easy remodeling when they are used as artificial skin, artificial tendon, artificial bone, surgical suture or the like. They also have an effect that they do not leave a prominent scar when the wound has been cured. Further, the biomedical materials of the invention are excellent in mechanical strength. Thus, when used as artificial skin, they are hard to tear, good for tightly adhering and capable of following the movement of a joint well.</p> |
