Bacteria-Killing Conductive Plastics

Bacteria-Killing Conductive Plastics
Aug-19-17
Conductive plastics able to prevent bacteria growth could offer a new way to reduce infections in hospitals.

Developed by a team at the Swedish Medical Nanoscience Center, the bacteria-fighting plastics combine the abilities of electrical currents and silver, both of which can kill bacteria, but can also be a human health risk at high concentrations.

To safely take advantage of the silver ions and electricity’s abilities, the team embedded silver nanoparticles into a plastic surface. Although the silver was not enough to kill bacteria on its own, a very small electric current sent through the material elevated its effectiveness enough to kill S. aureus, and prevent it from growing on the surface.
