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.
本发明提供了一种由鲨鱼源胶原组成的生物医学材料;一种由鲨鱼源胶原和羟基磷灰石组成的生物医学材料;以及制备方法。由于本发明的生物医学材料包含一种抗原性低、生物相容性高的鲨鱼源胶原蛋白,因此在用作人造皮肤、人造肌腱、人造骨骼、手术缝合线或类似材料时,不会产生排异反应,并能产生良好的生物粘附性和易于重塑的效果。它们还具有伤口愈合后不会留下明显疤痕的效果。此外,本发明的生物医学材料具有优异的机械强度。因此,当用作人造皮肤时,它们不易撕裂,粘合紧密,并能很好地跟随关节运动。
