We can learn from the unique structures of shark skin that give it its anti-bacterial property. Without the use of chemicals, anti-biotics or drugs, this innovation may potentially be extremely useful in the case of superbug (drug resistant bacteria) outbreaks. It is the structure of sharkskin’s surfaces that makes it inherently anti-bacterial. The thousands of microscopic ‘backwards diamond-shaped pointing ridges grooves and ridges’ makes it extremely difficult for bacteria to attach to the surface. The Navy have implemented this surface design to prevent barnacles and other marine life from attaching to the hull of the warships. This solved the issue of increased drag without killing excess marine life as the previous toxic biocide did. It is now possible to buy shark-skin textured films to attach to frequently interacted surfaces as a non-toxic way to prevent microbial spread, and these have been implemented in many hospitals.
