Could Nanotechnology End Cartilage Loss?

Scientists have long wrestled with how to aid those who suffer cartilage damage and loss. One popular way is to inject an artificial gel that can imitate cartilage's natural ability to act as the body's shock absorber. But that solution is temporary, requiring follow-up injections. Now nanotechnology engineers have shown, for the first time, how a surface of carbon nanotubes combined with electrical pulses could help regenerate cartilage naturally in the body.
