生物材料biomaterials概念理解

关于生物材料的一些概念说法:

1、维基百科定义生物材料:A biomaterial is any matter, surface, or construct that interacts with biological systems.

2、Park和Lake 定义生物材料为:Materials of synthetic, as well as of natural origin, in contact with tissue, blood and biological fl uids and intended for use for prosthetic, diagnostic, therapeutic and storage applications without adversely affecting the living organism and its components.(1999年)

3、Williams关于生物材料是这么说的:A material (other than drug) or a combination of materials intended to interface with biological systems to evaluate, treat, augment, or replace any tissue, organ or function of the body.

4、Bhat定义生物材料(2005年):A biomaterial is a synthetic material used to replace a part of the body and is in contact with living tissue.

5、Bronzino的理解:Generally, a biomaterial should work in harmony with its new biological environment (2000年). 所以假肢不算生物材料。

6、百度百科对生物材料的定义是:生物材料用于人体组织和器官的诊断、修复或增进其功能的一类高技术材料,即用于取代、修复活组织的天然或人造材料,其作用药物不可替代。生物材料能执行、增进或替换因疾病、损伤等失去的某种功能,而不能恢复缺陷部位。

(注)常见的生物材料主要分为四类:金属、聚合物、陶瓷和复合材料。
