Bone-growing nanomaterial could improve orthopaedic implants
Date:9/22/2007

y or undergo a bone scan to monitor bone growth.

Webster thinks these biosensing implants could even be designed to detect infection and be specially coated to release antibiotics or other drugs into the body.

Webster said the biosensing concept would work because when cells make calcium, an electrical current is created. That current can be conducted through carbon nanotubes and transmitted via radio frequency to a handheld device outside the body a similar process to the one employed by state-of-the-art cardiac pacemakers.

This technology would be incredibly exciting, Webster said. It could significantly improve patient health and cut down on expensive diagnostic tests and surgery. We still have a long way to go to make an intelligent implant a reality, but our new results are a strong first step.
