At Murdoch University in Perth, scientists have created a material that closely mimics the structure and composition of real bones. The new material, which they have dubbed “nano bone,” could revolutionize joint replacement surgery by making artificial titanium implants a thing of the past.

Each year, artificial implants made mostly of titanium are inserted into the hips and knees. One of the risks associated with joint implants is the possibility of infection.

Murdoch's scientist, Dr. Gérrard Poinern, has created a new mineral powder formula made from the main component of bone: a ceramic called hydroxyapatite (HAP).

"Hydroxyapatite is chemically similar to the mineral component of bone and hard tissues in mammals that give bones their strength," he noted.

"The‘ nano-bone ’material could potentially replace the traditional titanium joints with a nano-bone plate, better accepted by the body."

"Nanobone implants have a greater ability to interact with living tissues and allow the body to repair itself much faster, since it recognizes a similar nanomaterial and tries to develop in it," Gerrard said.
