Copper-coated implants reduce prosthesis associated infections

A surgical implant has demonstrated an 87% success rate in eradicating the bacteria responsible for staph infections in laboratory trials.

Utilising cutting-edge 3D printing techniques, a team of researchers at Washington State University (WSU) augmented the typical titanium alloy used in implants with 10% tantalum, a metal resistant to corrosion, and 3% copper.

The presence of copper on the material’s surface ruptures the cell walls of bacteria upon contact, while tantalum promotes healthy tissue growth, accelerating the healing process.
