Explanation

The biological environment refers to the conditions or conditions in the biological system where biomedical materials are located, including body fluids, organic macromolecules, enzymes, free radicals, cells and other factors in contact with materials. These factors can be affected by the composition and properties of materials themselves, for example, the degradation products of materials may change the pH value and composition of adjacent body fluids. In addition, the biological environment is also affected by many factors, such as animal species, implantation location, application target, surgical design and degree of trauma. Even if materials with the same properties are used in different applications, such as implantation in different parts, their biological environment will be different. biomedical materials need to function in the biological environment and interact with the biological system. Therefore, the biological environment plays a decisive role in the successful application of materials. When evaluating biological materials, it is very important to select correct experimental conditions and consider biological environmental factors, because these factors will affect the performance and feasibility of materials.
