2. Tissue engineering uses an artificially stimulated cell proliferation by using suitable supports made of nanomaterials, and growth factors. As an example, the bone can be grown again on the supports of the carbon nanotubes. Tissue engineering may replace today's conventional methods of treatment such as organ transplantation or artificial implants. Advanced forms of tissue engineering can lead to life extension. Also of nanocrystals made of calcium phosphate artificial bone composites.

3. Creating solids and surfaces with a modified molecular structure. In practice, this gives metals, inorganic and organic compounds, nanotubes, biocompatible polymers (plastics), and other materials simulating living tissues, serving vehicles drug delivery devices, implants, grafts.

4. Nanotechnology helps to promote the use of arthroscopy, which is a device the size of a pencil and used in surgery with a light and camera that allows surgeons to do surgery with smaller incisions. The smaller incisions, faster treatment is best for patients. It also helps to find a way to make the arthroscope is smaller than a strand of hair.
