Infected implants now have a foe. Brown University researchers have created a nanoparticle that can penetrate a bacterial-produced film on prosthetics and kill the bacteria. The finding, published in the International Journal of Nanomedicine, is the first time that iron-oxide nanoparticles have been shown to eliminate a bacterial infection on an implanted prosthetic device.

Nano “cannonballs” bash infected implants
Patients suffering from infected prostheses may now have an ally in tiny “cannonballs.” The nanoparticles created by graduate student Erik Taylor and engineering associate professor Thomas Webster have been shown in lab tests to kill bacteria that congregate on implants.
