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 healthcare. 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 percent of all bacteria on a surface. Healthcare-associated infections are a widespread problem around the world, causing great suffering, high healthcare costs and a heightened risk of increased antibiotic resistance .
Most infections occur in connection with the use of various medical technology products such as catheters, hip prostheses, knee prostheses and dental implants, where bacteria are able to enter the body via a foreign surface. At Chalmers University of Technology, researchers have been exploring how graphene, an atomically thin two-dimensional graphite material, can contribute to the fight against antibiotic resistance and infections in healthcare. The research team has previously been able to show how vertically standing graphene flakes prevent bacteria from attaching to the substrate.
Instead, the bacteria are cut to pieces on the razor-sharp flakes and die. We are developing a graphene-based, ultra-thin, .
