Biomaterials are a class of high-tech materials used to diagnose, repair, or enhance their function in human tissues and organs, that is, natural or man-made materials used to replace and repair living tissues, and their effects are irreplaceable. Biomaterials can perform, enhance, or replace a function that is lost due to illness, injury, and so on, but can not restore a defective site.

Biomaterials are widely used and there are many varieties and classification methods for them. Biological materials include metal materials (such as alkali metals and their alloys, etc.), inorganic materials (bioactive ceramics, hydroxyapatite, etc.) and organic materials. Organic materials are mainly polymer aggregate materials. According to the material properties, polymer materials are usually divided into synthetic materials (polyurethane, polyester, polylactic acid, polyglycolic acid, lactic acid glycolic acid copolymer, other medical synthetic plastics and rubber) and natural macromolecules (such as collagen, silk protein, cellulose, chitosan, etc.). According to the usage of materials, polymer materials can be divided into bioinertmaterial, bioactive material and biodegradable material. Macromolecule material, depending on whether the degradation products can be metabolized and absorbed by the body, degradable polymers can be divided into bioabsorbable material and bio-non-absorbable material. According to the influence of the material to the blood, the polymers are classified into blood compatibility and the blood incompatibility. According to the affinity and reaction of the material to the body cells, it can be divided into biocompatible and bio-incompatible polymers.

Different types of biological materials. The four pictures shows four biological materials-biological metal materials, biological ceramicmaterials, prosthetic valves, cochlear implant.

Biological materials are mainly used in people, and the requirements of that are very strict and must have four characteristics:

Biological functionality: Functionality refers to a series of properties that a biological material should possess or complete with a corresponding biological function. For example, as a slow release drug, drug release performance is its biological functionality.

Biocompatibility: Biocompatibility can be summarized as the relationship between material and living body, including blood compatibility and histocompatibility (non-toxic, non-carcinogenic, pyrogen-free reaction, no immune rejection, etc.).

Chemical stability: Resistant to biological aging (particularly stable) or biodegradable (controlled degradation).

Machinability: Machinability means that the material can be molded and disinfected (UV sterilization, high pressure boiling, ethylene oxide gas disinfection, alcohol disinfection, etc.).
