生物材料又称生物工艺学或生物技术。应用生物学和工程学的原理，对生物材料、生物所特有的功能，定向地组建成具有特定性状的生物新品种的综合性的科学技术。生物工程学是70年代初，在分子生物学、细胞生物学等的基础上发展起来的，包括基因工程、细胞工程、酶工程、发酵工程等，他们互相联系，其中以基因工程为基础。只有通过基因工程对生物进行改造，才有可能按人类的愿望生产出更多更好的生物产品。而基因工程的成果也只有通过发酵等工程才有可能转化为产品。 医学上通过生物工程可以生产出大量廉价的防治人类疾病的药物，如入胰岛素、干扰素、生长激素、乙型肝炎疫苗等。生物工程在食品、轻工中的应用面也很广。1983年美国用生物工程生产的用于制作饮料的高果糖浆的年产量达600万吨，从而使蔗糖的消耗量减少一半。采用生物工程技术，使育种工作发生了很大变化，如把抗病基因转移到烟草中去，已培育出防止害虫的烟草新品种；把低等生物根瘤菌的固氮基因转移到高等作物的细胞中，使之能自己制造氮肥，也取得了一定成果。目前世界各国对生物工程十分重视，我国也把生物工程列为重点发展的科研项目之一。生物工程学的研究将对人类的生产方式和生活方式产生巨大的影响。 [ Last edited by sunbuct on 2008-9-24 at 15:07 ] |

The development of biomaterials is not a new area of science, having existed for around half a century. The study of biomaterials is called biomaterial science. It is an exciting field of science, having experienced steady and strong growth over its history with companies such as Smith and Nephew investing large amounts of money in new products. Biomaterials science encompasses elements of medicine, biology, chemistry and materials science. Biomaterials are used in: Joint replacements Bone plates Bone cement Artificial ligaments and tendons Dental implants for tooth fixation Blood vessel prostheses Heart valves Skin repair devices Cochlear replacements Contact lenses Biomaterials must be compatible with the body, and there are often issues of biocompatibility which must be resolved before a product can be placed on the market and used in a clinical setting. Because of this, biomaterials are usually subjected to the same requirements of those suffered by new drug therapies. All manufacturing companies are also required to ensure traceability of all of their products so that if a defective product is discovered, others in the same batch may be traced. |
