Biocompatibility is a field of research that focuses on the interactions between biomaterials and biological systems, such as cells, tissues, and organs. The goal of biocompatibility research is to develop materials and devices that can safely and effectively integrate with the body without causing negative reactions or harm. This involves studying the physical, chemical, and biological properties of materials to ensure they are compatible with living tissues and do not elicit toxic, inflammatory, or immunological responses. Biocompatibility research is essential for the development of medical implants, drug delivery systems, tissue engineering scaffolds, and other biomedical technologies.
