What is a medical active biomaterial?

Biomaterials are sometimes called biomedical materials. According to the definition of biomaterials put forward by the International Organization for Standardization (ISO) in June, 5438+0987+00, biomaterials generally refer to inanimate materials that are used to contact with living tissues in medicine and can achieve certain functions, including materials with good biocompatibility, biodegradable materials and non-biodegradable materials.

Professor Hench, a famous expert on biomaterials, divided the development of biomaterials into three stages:

The first generation is biologically inert materials,

The second generation is bioactive materials and degradable materials.

The third generation is biomaterials that can stimulate cells to produce special reactions at the molecular level.

Combined with the development situation at home and abroad and China's national conditions, the short-term and medium-term strategic goal of biomaterials in China should focus on the second generation of bioactive materials and develop a number of new products with independent intellectual property rights.
