Graphene to Disrupt Biofilms on Dental Implants

Graphene the basic structural element of allotropes of carbon, such as graphite, charcoal, carbon nanotubes and fullerenes. It is also the major research topic in the arena of Materials Science and Engineering, Nanomaterials. Scientists established that the layer of graphene can form a protective film on the surface of implants that can prevent bacterial infection.
Systems, for example, dental implant or knee substitution surgery always carries a danger of bacterial infection. Microorganisms that enter the body circulate in liquids, such as, the blood, and discover surfaces to stick to. Once joined, they multiply to frame a protective "biofilm" that can once in a while, stop an implant appending to bone.

As revealed in the journal Advanced Materials Interfaces, analysts at Chalmers could show that a layer of vertical graphene chips can frame a defensive layer over the surface of the implant, hindering bacterial attachment. The sharp graphene flakes cut the microscopic organisms apart and destroy them. Coating Implants with this defensive layer could eliminate the use of antibiotics, prevent from infection, also reduce the risk implant rejection. The flakes don't harm human cells because those cells are so considerably larger (25 µm in diameter) than bacterial cells (1 µm in diameter).

Graphene has high potential for health applications. But, more research is required before we can claim it is completely safe. In addition to other things, we realize that graphene does not degrade easily.
