Shark Skin-Like Surface Fights MRSA

Surfaces covered in a micropattern mimicking the ridges of shark skin could reduce the spread of drug-resistant Staphylococcus aureus and other superbugs in hospitals.

FLICKR, ELIAS LEVYWith the rise of microbes that have evolved resistance to even the most powerful antibiotics, researchers are getting creative. One solution: develop materials with microscopic surface textures that kill bacteria or prevent them from latching on. The nanoscale spikes of an insect’s wing, for example, have been shown to be potent killers of Pseudomonas aeruginosa, and a new study points to the bacteria-fighting promise of a surface texture that mimics shark skin.

Known as Sharklet, the pattern consists of an arrangement of microscopic ridges that resemble the tooth-like structures, or denticles, of shark skin. According to the study, published today (September 17) in Antimicrobial Resistance and Infection Control, Sharklet reduced methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant S. aureus (MRSA) by as much as 97 percent and 94 percent, respectively, compared to smooth controls.

“The Sharklet texture is designed to be manufactured directly into the surfaces...
