First, the functionality of biomaterials.
Refers to a series of properties that biomaterials should have when they have or complete a certain biological function. According to the purpose, it is mainly divided into the function of bearing or transmitting load. Such as artificial bones, joints and teeth. The function of control that flow of blood or body fluids. Such as artificial valves and blood vessels; Electrical, optical and acoustic conduction functions. Such as pacemaker, intraocular lens, cochlea, etc. Filling function. Such as fillers for cosmetic surgery.
Second, the compatibility of biomaterials.
Refers to the ability of biomaterials to function effectively in or on the body surface for a long time. It is used to characterize the biological behavior of biological materials interacting with organisms in vivo.
According to the contact position between materials and organisms, it is divided into blood compatibility. This material is used in the contact between cardiovascular system and blood, mainly to investigate the interaction with blood; Contact with tissues and organs outside the cardiovascular system. Mainly investigate the interaction with tissue, also known as general biocompatibility; Mechanical compatibility. Examine the consistency between mechanical properties and organisms.
Development of biomaterials;
Biomaterial science's technology has developed rapidly. Even in the current global economic downturn, biomaterials still maintain a high growth rate of 13% every year, which fully reflects its strong vitality and broad development prospects. Modern medicine is developing in the direction of regeneration and reconstruction of damaged tissues and organs, recovery and improvement of human physiological functions, personalized and minimally invasive treatment.
Traditional inanimate medical materials such as metals, polymers and bioceramics can no longer meet the requirements of medical development, and biomedical materials science and engineering are facing new opportunities and challenges. In the future, the market share of biomedical materials is likely to catch up with drugs.
Therefore, it is urgent to strengthen the clinical application research and popularization of biomedical materials, and focus on developing the integrated system of R&D, production and marketing of biomedical materials in China. In fact, China has made a great breakthrough in basic research in biomaterial science and is one of the advanced countries in the world. However, the level of industrialization needs to be improved, and the industrial scale is small.
