Danger Dust

With strong bactericidal properties, graphene has the potential to become a game changer in the fight against antibiotic-resistant bacteria. So far there have been no efficient ways to control these properties—and thus no way to make use of graphene's potential in health care.

Now researchers at Chalmers University of Technology, in Sweden, have solved the problem by using the same technology found in an ordinary fridge magnet. The result of which, is an ultra-thin acupuncture-like surface that can act as a coating on catheters and implants—killing 99.99% of all bacteria on a surface.

Unpreceded efficiency by controlling magnetic fields

By arranging earth magnets in a circular pattern making the magnetic field inside the array arrange in a straight direction, the researchers were able to induce a uniform orientation of the graphene and reach a very high bactericidal effect on surfaces of any shape.
