(Summary description)Physical methods dominated the discovery and preparation of new materials for most of the first half of the 20th century. Since the 1950 s, the idea and way of molecular biology was quickly recognized as new material growth, discovery, and the crystallization of the guiding ideology, because most of the biological reaction occurred in the material interface and on the surface, biologists will introduce a surface science biology, to promote the development of biomedical materials play a decisive role, biomedical materials and devices in the rescue ability of human's life, as well as the huge commercial value strongly stimulate the study of many channels. Low temperature plasma technology on the growth of biomedical materials and the preparation of biomedical device has unique advantages and potential, therefore, if the biomedical and organic integration of low temperature plasma technology is likely to lead to the development of biomedical technology in the 21st century revolutionary, biomedical materials refers to the involved in biomedical research and medical practice and biological compatibility of materials, including materials, biosensor materials to make artificial organs, in vivo transplantation device outside surface materials, as well as some of the medical equipment used by material, , etc., most organisms on the material on the surface of the reaction is controlled by the surface of the material chemistry and molecular structure, which requires the biomedical materials not only need to have a certain strength, elasticity, such as liquid, has the biological compatibility of surface properties and requirements, a new design of the liquid and the surface characteristics of materials at the same time with the required is quite difficult, since the biological response to the material surface mainly depends on the material surface chemical properties and molecular structure, you can choose the existing with the required liquid material surface modification, make its surface has the required biological compatibility, For example, some macromolecular polymers have mechanical properties similar to human organs, but they do not have biological compatibility. Therefore, surface modification is needed to fix specific functional groups on the surface to achieve compatibility with living bodies. In addition, we can have a choice of material surface modification, make it has a specific function, which requires to change and control of surface functional groups, we will be this kind of surface modification of existing materials to the right to obtain corresponding biological compatibility method called interface design, interface design of various materials of biological origin have different challenge, the challenge comes from the surface of the different functions and to identify the organism, according to the demand to choose suitable functional group, and to choose appropriate technology introduces the functional groups on the surface of, for many of the existing materials, plasma polymerization and plasma polymerization combined with grafting technology, It is a very effective and economical surface modification technology, and has been paid more and more attention and interest by the biotechnology and engineering circles. The characteristic of this technology is that the surface properties can be changed by selectively changing the functional groups of the surface, so as to achieve the required surface properties.
