Biomedical engineering, or medical engineering is the application of engineering principles and design concepts in medicine and biology for healthcare purposes (such as diagnostic or therapeutic).
As using nanotechnology, it is possible not only to modify existing natural materials, but also create new materials with desired properties, they are seen as a source of conscious design of both risks and desirable properties of nature.
Conclusion Compared to many other fields of engineering, biomedical engineering has recently become a separate study.
