AZoNano notes that nanoscale materials science is helping to produce better implants and artificial replacements for body parts. The field of prosthetics competes with regenerative medicine to better repair age-related damage. Here, we see advances in developing materials that will better integrate with tissue in the body. If you can get an artificial hip that is stronger than titanium, bonds more completely with surrounding tissue, and never wears out, why would you want to just regenerate the old bone structures? New materials like these raise interesting possibilities for ways in which we can extend the durability and age-resistance of our bodies.
