Implants And Prosthetics

In the coming years, patients may receive hip implants and other bone implants that employ nanotechnology. As an example, one research group has created a microsensor for patients recovering from hip replacement and other joint related surgery.

The nanotechnology sensor is permanently implanted with the joint implant. The self-powered wireless microsensor monitors the bone healing process after surgery. During the healing process, the device measures and compares how the bone grows and attaches to the pores on

Most animal cells are 10,000 to 20,000 nanometers in diameter. This means that nanoscale devices, having at least one dimension less than 100 nanometers, can enter cells and the organelles inside them to interact with DNA and proteins.

the surface of the implant. It records how the patient is healing and when the patient can resume normal activities.

This technology will not only monitor bone healing at the time of surgery but also can determine when implants are worn out and need to be replaced. The average lifetime of implants is about 15 years. Therefore the microsensor will be valuable throughout the patient's lifetime for observing and maintaining the health of the implant.
